*That Time Brenda from HR Nearly Emailed Our Payroll Info to a Nigerian Prince * Ah, the innocence of small business life. When we launched our boutique agency, we were five people, two laptops, one French press, and exactly zero plans for cybersecurity. Our “IT strategy” was “Don’t click on weird stuff.” Solid, right? Then came the day Brenda got an email from “our CEO” (spoiler: it wasn’t me) asking for all W-2 forms immediately. She almost sent them. I almost fainted. That’s when we realized: we may be small, but hackers? They love small. Why? Because we’re usually under-protected, over-trusting, and too busy running a business to check if "google support" is legit. Cybersecurity is not a policy—it’s a mindset.

Introduction When working with Git, keeping a clean and linear commit history makes collaboration easier. By default, git pull performs a merge, which can create unnecessary merge commits and clutter your history. A better alternative is git pull --rebase, which rewinds your local changes, applies the latest remote changes, and then replays your commits on top. This keeps your history linear and easier to follow. In this guide, we'll explore how git pull --rebase works, when to use it, and some best practices to avoid common pitfalls. git pull --rebase Works Normally, git pull does two things: Fetches changes from the remote (git fetch). Merges them into your branch (git merge), creating a merge commit. With git pull --rebase, Git: Fetches the latest changes (git fetch). Temporaril…  ( 7 min )

In this Story, I have a super quick tutorial showing you how to create a multi-agent chatbot using LangGraph, Knowledge Graph, and Long Term Memory to build a powerful agent chatbot for your business or personal use. If you’ve worked on the RAG project, you’ve likely encountered the issue of how static knowledge bases can limit the system’s ability to handle new or changing information. RAG systems rely on these knowledge bases, which are fixed and don’t update based on new user interactions. This is similar to how graph and relational databases have different data structures, making it hard to compare or translate queries between them.

If you’re doing a lot but not seeing results, here’s what helps me: instead of trying everything at once, I look for the one main thing that’s blocking progress — and focus only on fixing that. This gives the biggest impact. For example, You focus on what’s comfortable — not on what’s important. Beginner entrepreneurs with a background in coding or analytics struggle to make sales. The real reason: no one is visiting their website. Instead of doing marketing to get their first 1,000 users, developers keep improving the product, and analysts keep polishing data tracking. But if no one sees the product, none of that matters. Progress begins when you find and remove the main obstacle — not when you do everything or stick to what’s familiar. This idea comes from the book The Goal by Eliyahu G…  ( 4 min )

Users access web applications through various browsers, devices, and operating systems. Whether it’s Chrome on Android, Safari on macOS, or Firefox on Linux, modern web experiences must deliver consistent performance across all environments. One rendering issue or functionality glitch can break the user experience and push customers toward a competitor. That’s why browser testing tools have become essential for ensuring the success of web apps. The same HTML, CSS, and JavaScript code can behave differently depending on the browser and platform. Factors like rendering engines, support for web standards, and device-specific quirks make it nearly impossible to predict how an application will perform without rigorous testing.

Factory-Floor Lessons in Reshaping Software Innovation ‍Hierarchy on the Floor In the early 20th century, manufacturing was organized with a rigid hierarchy. Managers and engineers made all significant decisions, while front-line workers were expected to "do as they're told," performing narrow tasks without input into process or strategy. Factory workers, often seen as low-status laborers, had little agency beyond their assigned duties. This division meant that problem-solving and innovation were the sole province of experts and senior staff, not the rank-and-file. By the 1930s, the typical American steel mill or machine shop exemplified this top-down structure. Workers on the shop floor desired better pay and conditions, but companies struggling through the Great Depression h…  ( 6 min )

"JavaScript is a language of many paradigms. It borrows ideas from functional programming, object-oriented programming, and procedural programming." Kyle Simpson Why does JavaScript feel... different? Every developer has that moment. You're writing code, everything seems logical, and then JavaScript does something that makes you pause and think: "Wait, that actually worked?" A variable becomes a function. An object transforms mid-execution. Async operations flow like water. Other languages demand you follow their rules. JavaScript asks: "What are you trying to accomplish?" Then it finds a way — often multiple ways — to make it happen. This isn't accident. It's intentional design philosophy that emerged from a simple truth: the web is chaotic, unpredictable, and constantly changing. So J…  ( 9 min )

Instructions: Given two arrays a and b write a function comp(a, b) (orcompSame(a, b)) that checks whether the two arrays have the "same" elements, with the same multiplicities (the multiplicity of a member is the number of times it appears). "Same" means, here, that the elements in b are the elements in a squared, regardless of the order. Examples b = [121, 14641, 20736, 361, 25921, 361, 20736, 361] a = [121, 144, 19, 161, 19, 144, 19, 11] a = [121, 144, 19, 161, 19, 144, 19, 11] b = [132, 14641, 20736, 361, 25921, 361, 20736, 361] a = [121, 144, 19, 161, 19, 144, 19, 11] b = [121, 14641, 20736, 36100, 25921, 361, 20736, 361] Remarks Thoughts 1: Initially, I approached the problem by checking if each number from the first array, when squared, exists in the second array.

A major breakthrough in cancer care is making headlines. Scientists from the US, UK, and Switzerland have developed a cutting-edge test that predicts which men with aggressive, non-metastatic prostate cancer are most likely to benefit from the drug abiraterone. This is significant because while abiraterone can save lives, it also causes serious side effects such as high blood pressure, diabetes, and heart complications. Until now, doctors had no reliable way to know who should receive the drug. This new test, powered by machine learning, changes that. It analyzes digital images of tumor biopsy samples and identifies a specific biomarker that indicates whether a patient is likely to respond to treatment. In a study involving over one thousand men, the test found that twenty five percent of them had this biomarker. For these patients, abiraterone reduced the risk of death within five years from seventeen percent to nine percent. For the rest, the drug showed little to no effect, meaning they could avoid unnecessary treatment and side effects. The test is designed to work with routine clinical data and can easily be added to existing hospital workflows. It promises to make prostate cancer treatment more precise, sparing patients who do not need aggressive therapies and ensuring those who do get the help they need. Researchers also hope the findings will encourage broader approval of abiraterone for early-stage use, especially in the UK where its application has been limited. With this test, the decision becomes more scientific, more ethical, and far more personal.

When building secure APIs or applications with OAuth 2.0, validating access tokens is a critical step. Two common approaches for token validation are JWKS (JSON Web Key Set) and the Token Introspection Specification (RFC 7662). Each has its strengths, use cases, and trade-offs. In this blog post, we’ll explore both methods, compare their pros and cons, and help you decide which is best for your system. Purpose: Validates JSON Web Tokens (JWTs) locally. How It Works: The authorization server exposes a JWKS endpoint (e.g., /.well-known/jwks.json) containing public keys. The resource server uses these keys to verify the JWT’s signature and checks claims like expiration (exp), issuer (iss), and audience (aud). Key Feature: No network call is needed for validation after caching the JWKS, making…  ( 6 min )

Why are there so many JavaScript build tools? Gulp, Grunt, Webpack, Laravel Mix, Rollup.js, and now Vite. And these are just the ones that I've worked with. Haven't we solved this problem? And why build a new tool? Why not improve existing tools? I think about predecessors like GNU Make. Sure, it's old, but it's tried and true. The invocation is consistent and has been for years: make [command]. How different would the world be if the Node.js ecosystem adopted Make as the preferred mechanism for running scripts, instead of npm run [command]?

Introduction The test failed. Of course it did. And now you're in a staring contest with a stack trace that refuses to make sense. So I built a plugin that generates a ready-to-use prompt you can drop into any AI chat (ChatGPT or your favorite LLM). It packs in all the useful context: test steps, environment info, error messages, and stack traces, so the AI actually gets what happened. No digging through logs. No re-explaining your setup. Just click "Copy Debug Prompt", paste it into ChatGPT, and get help that makes sense. The plugin hooks into Cypress's failure handling. When a test fails, it captures the error message, test title, relevant stack trace, and even the surrounding context, then wraps it all into a clean, AI-friendly prompt. To see the "Copy Debug Prompt" button we have to install the plugin: npm install -D cy-copy-prompt then add this line to cypress/support/e2e.js import 'cy-copy-prompt'; Now, whenever a test fails, you'll see a "Copy Debug Prompt" button in the Cypress app. One click, and your clipboard is loaded with a prompt that's ready to paste into AI chat. Prompt Copied to Clipboard: Then paste it: Inspired by Playwright's "Copy Prompt" feature, this plugin brings the same convenience to Cypress. It's simple, helpful, and open source. Try it out. If you like it, star it, fork it, or suggest a tweak.  ( 3 min )

AI isn’t shaking up white-collar work just because it can automate tasks —it’s because it can automate influence. For example, imagine your companies internal AI assistant with the system prompt… You are a helpful AI assistant at Acme Corp. Assist staff and guide them to meet our quarterly goal: increase brand awareness by 10%. Congrats. You’ve turned the assistant into a corporate hypnotist. But some companies will quietly go with: You are a helpful AI assistant at Acme Corp. Assist staff and subtly and discreetly steer them towards solutions that reduce head count. Invisible bias, wrapped in a smiley assistant. Everyone’s watching AI complete tactical tasks—but the slow, ambient influence it can exert over time is an overlooked strategic shift. - Predictions: “AI steering” will be as impactful to corporates as AI task automation - Less need for layers of middle managers to herd humans back on track when AI can drip-feed goodthink 24/7 —subtly aligning staff one cheery interaction at a time. Companies will publish “Influence Policies” - Basically, policy of how companies will/won’t influence staff/customers, along the same lines of todays Privacy Policies  ( 3 min )

When talking about cryptocurrencies and blockchain, it's common to hear that your wallet is just a pair of keys: a private key and a public key. But how exactly is a public key generated from a private key? And how does that turn into a Bitcoin address? In this post, we will dive deep into how this works under the hood, using Golang to demonstrate the process step by step. A private key is simply a very large number. Seriously. Just a random number between 1 and the maximum allowed by the elliptic curve (secp256k1 in Bitcoin). The more random, the better. You can generate it from mouse movements, atmospheric noise, or even the lottery draw. But for simplicity, in this example, we'll derive it from a passphrase (which is, of course, not secure in real-world applications). Let's generate a p…  ( 4 min )

Hi, I have created a Subscribe Notify pattern, that greatly simplifies dealing with Observables (eg. for HttpClient), in your component. The pattern is implemented by a Notification Service which subscribes to the Observable and wires up the data & error received, to streams. These streams (data$ & error$) are assigned to local variables (employees$ & error$) in your component. These variables re-render the mark up every time they are notified & updated with new data or error. component.ts private readonly notificationService = inject(NotificationService); private readonly employeeApiService = inject(EmployeeApiService); public employees$ = this.notificationService.data$; public error$ = this.notificationService.error$; getEmployeesByName(searchName: string) { // Fetch employees by name. // The employeeApiService method returns an Observable. // The employees$ stream will be notified and updated with the data. // The error$ stream will be notified and updated with the error if any. this.notificationService.subscribe ( this.employeeApiService.getEmployeesByName(searchName) ); } component.html @if (error$ | async) { {{(error$ | async)?.message}} Name Total Leave Days {{ employee.name }} {{ employee.totalLeaveDays }} } Real easy to implement in your solution.

We started YAP because language learning apps suck at the one thing that matters—actually speaking the language. If you've ever opened Duolingo for 100+ days straight but still froze during a real conversation, you're not alone. Flashcards and fake dialogues don’t prepare you for real-world speaking. YAP flips the model. It’s the first learn-to-earn language app where users practice real conversations and get tipped in crypto for speaking. We reward fluency, not memorization. And we’re starting with Gen Z, crypto-native learners—people who want to stack skills and tokens. We’re a small team of two (a non-technical -- me, and a technical co-founder).

This type of noise randomly alters certain pixels in the image by setting them to the minimum or maximum possible intensity values (e.g., 0 and 255 in 8-bit images), while the rest of the pixels remain unchanged. Applying a Gaussian filter in these cases is counterproductive. Convolution with a Gaussian kernel smooths the image through a weighted averaging operation, which affects both noisy and non-noisy pixels. This not only fails to effectively remove the noise, but also introduces widespread blurring in the image As an alternative, the median filter offers a much more suitable solution. This filter replaces the value of each pixel with the median of the intensity values of its neighbors within a local window (typically square-shaped). By focusing on the central value of the sorted data, the median filter preserves edges and is highly effective at removing outliers such as those introduced by salt-and-pepper noise. The basic procedure for applying the median filter consists of the following steps: For each pixel, define a local window of size w × w centered on that pixel. 2.Extract all intensity values within that window. 3.Sort the values. 4.Replace the central pixel value with the median of the sorted list.

Transforming Design Workflows with AI AI is really changing how design teams get things done. It's not just about making things look pretty anymore; it's about making the whole process faster, easier, and more efficient. Think about it: less time spent on boring, repetitive tasks means more time for actual creativity and innovation. It's a win-win. Seamless Cross-Platform Design Innovation One of the coolest things about AI in design is how it breaks down platform barriers. No matter if you're working with mobile app screenshots or website mockups, AI can handle it. This means designers can quickly adapt to different design needs without getting bogged down in technical details. It's all about flexibility and speed. Quickly respond to design needs across different platforms. Enhance work e…  ( 5 min )

In the first post of this series, we explored why AI apps need security from the very beginning. Today, let’s dive into something more hands-on: threat modeling. If you're not familiar with the term, think of threat modeling as the process of asking, “What can go wrong?” before your AI app is exposed to the real world. For AI systems, this means looking beyond traditional vulnerabilities and into the unique risks that come with using models, training data, and user prompts. Threat modeling isn’t new. It’s been a common part of security practices for years. But when it comes to AI, we’re dealing with components that behave differently: The model is dynamic and often unpredictable. The data is unstructured and possibly user-generated. The logic isn’t just written in code — it’s embedded in w…  ( 5 min )

Recently, a CLI tool for visualizing Claude Code usage costs has been making waves in Japan. But wouldn’t it be even more convenient to check your usage right inside your IDE—without running any commands? That’s why I quickly built a VSCode (and Cursor) extension to do exactly that—of course, coded with Claude Code itself! Source code and install instructions are here: https://github.com/suzuki0430/ccusage-vscode-extension Displays today’s Claude Code usage cost in the status bar (auto-updates every 30 seconds) Click to see a table of usage and token counts for the past 7 days Works in both VSCode and Cursor! Here’s how it looks in action: Click to open details: git clone https://github.com/suzuki0430/ccusage-vscode-extension.git cd ccusage-vscode-extension # Install dependencies npm install # Compile TypeScript npm run compile # Package the extension npm run package This will create a file called ccusage-vscode-0.1.0.vsix in your current directory. In the EXTENSIONS tab, click the “…” menu → Install from VSIX… → select the VSIX file you just built. After importing, the cost will appear in the status bar. (If it doesn’t, try restarting VSCode.) Simply drag and drop the VSIX file into the EXTENSIONS sidebar. Whether you’re worried about overusing the Claude API or just want to check if your MAX plan is worth it, this extension makes it super easy to keep an eye on your costs. https://github.com/ryoppippi/ccusage  ( 3 min )

There's a new HTTP framework in the Bun ecosystem that's worth checking out: Verb. It takes a refreshingly simple approach - leveraging Bun's built-in capabilities instead of reinventing the wheel. Verb is built directly on Bun's native HTTP server with zero external dependencies. This means you get the raw performance of Bun without any abstraction overhead. Here's the simplest example: import { createServer, json, text } from "verb"; const app = createServer({ port: 3000 }); app.get("/", () => text("Hello, Verb!")); app.get("/api/users/:id", (req, params) => json({ id: params.id })); That's a working server. No configuration files, no boilerplate. Verb uses an LRU cache for compiled route patterns. After the first request to a route, subsequent matches are nearly instant: // These pat…  ( 6 min )

Introduction When Next.js 13 introduced new capabilities to the native fetch API, it broke the way we used Axios in our web projects at Tractian. This is the story of how I identified the problem, led the creation of a new HTTP client—Traxios—and how this decision positively impacted our team and delivery. At Tractian, our web team relied heavily on Axios for all HTTP requests. Axios provided a familiar, ergonomic API, interceptors, and instance management, making it a staple in our codebase. However, with the release of Next.js 13, the native fetch API was extended with new options like cache and next, enabling advanced caching and revalidation strategies crucial for modern SSR/SSG applications. Unfortunately, Axios did not support these Next.js-specific fetch options. Using Axios meant…  ( 5 min )

I've been working on a small but complete side project in C# – a playable Blackjack game that runs entirely in the console. What started as a practice run to sharpen my .NET and clean coding skills turned into a minimal but functional card game, with some extra flair like card rendering and a basic AI bot. Here's a breakdown of the project and what I learned along the way. Console-based, cross-platform (runs on .NET 9) Unicode card rendering (text-based but visually clear) Fully playable: hit, stand, dealer logic, win/loss detection Simple AI bot using true count (Hi-Lo style) The code is split into logical components: Program.cs: main game loop, player input, win/loss handling Cards.cs: deck generation, card drawing, visual rendering Bot.cs: AI logic — currently uses a basic running count to decide whether to hit or stand The goal was to keep the structure clean and extensible, so it’s easy to maintain and improve. You can find the full source code here: 🔗 https://github.com/porzeraklon/blackjack It's open-source and self-contained — no dependencies besides the .NET runtime. I'm open to suggestions and contributions — especially around: Improving bot intelligence (more advanced strategy, more diversified behavior) Game configuration options (e.g. changing stakes, betting) GUI version later down the road If you check it out, feel free to leave feedback or open an issue. Hope it inspires someone else working on a similar idea. Thanks for reading!  ( 3 min )

An index helps MySQL find the data it needs without scanning an entire table. For a handful of rows, this might not seem important. But in a table with hundreds of thousands or millions of rows, the difference between having a lookup structure and lacking one can be dramatic. Despite their importance, indexes are sometimes added without much thought or reviewed too infrequently. As data and queries change, a search key that once helped may now be hurting performance. That’s why inspecting and understanding existing indexes is not just a task for optimization but an ongoing part of maintaining a healthy database. Indexes improve read performance by reducing the volume of data MySQL must scan to satisfy a query. Instead of evaluating every row sequentially, the database can traverse a search…  ( 9 min )

You’ve probably puzzled over this at some point in your career. Don’t worry — the answer is here. First of all, what do I mean by keeping unread notifications relevant? What’s the problem? Like a lot of things, it’s easier to explain with an example. Let’s say we have a system that helps you find people for upcoming job shifts. It sends a notification to someone asking if they want a shift on Saturday from 12 pm to 3 pm at a given address. A few people respond “yes,” you pick someone, and that person gets notified that they’ve got the gig. If the time of the shift changes or it gets cancelled altogether, the system sends them another notification. Now let’s zoom in. The job is offered.

We’ve all been there. You’re at a coffee shop, airport, hotel, or maybe your favorite mall—and boom, free public Wi-Fi pops up. It’s tempting, right? But before you connect and start scrolling, let’s talk about something most people ignore: public Wi-Fi safety. In this post, I’ll show you how to browse securely on the go, why it’s risky to trust open networks blindly, and some simple steps you can take today to protect your personal information. Public Wi-Fi networks are often unencrypted, open to everyone, and poorly monitored. That makes them an easy target for cybercriminals. Here’s what could go wrong: Hackers can intercept your data while you browse. You might connect to a fake hotspot (also known as an Evil Twin attack). Your personal info—passwords, emails, or even banking details—c…  ( 4 min )

Developer Relations é a área, ou a pessoa, que cuida do relacionamento com pessoas desenvolvedoras. Pode ser uma função específica dentro da empresa, uma equipe dedicada ou até um programa estruturado. “Para a empresa, eu represento a comunidade. Para a comunidade, eu represento a empresa.” O foco de DevRel não é vender um produto. É apoiar pessoas desenvolvedoras com o que elas precisam para terem sucesso: conteúdos que ensinam, suporte que resolve, espaços para troca e ferramentas que funcionam. É sobre criar conexões de verdade com quem está do outro lado do código. Quando bem feita, essa estratégia ajuda não só na adoção do produto, mas também na criação de uma comunidade que se sente parte da construção. Isso fortalece a confiança, abre espaço para feedback direto e estimula a inovaçã…  ( 4 min )

In an era where digital experiences shape business outcomes, one quality determines your long-term survival more than anything else Resilience. Your infrastructure could be bulletproof. Your application could be cloud-native. But can your system handle unpredictable traffic spikes, cascading failures, or regional outages? That’s where resilience testing steps in. What Is Resilience Testing? Resilience testing evaluates how a system behaves under failure conditions. It doesn’t just ask “Does it work?” but “What happens when it breaks?” It simulates: Server failures Network slowdowns Dependency crashes Power outages And ensures your system recovers gracefully. Why Is It Important? Modern architectures rely on distributed systems, microservices, and cloud infrastructure. These are fast and scalable but also more complex and interdependent. Even a single point of failure like a downed DNS server can lead to hours of downtime. Resilience testing identifies weak links before your users do. Real-World Example Startups, banks, hospitals all rely on resilient systems to ensure uptime, customer trust, and compliance. What Should You Test? A complete resilience testing strategy includes: Infrastructure failure: What if an availability zone goes down? Application failure: What if a microservice crashes? Network instability: Can services handle latency? Resource exhaustion: How does your system behave under stress? Best Practices Introduce failures gradually. Monitor everything latency, error rates, recovery times. Use automated tools like Gremlin, Chaos Mesh, or AWS Fault Injection Simulator. Always run post-mortems to fix root causes. What It Means for You If you're investing in uptime, user experience, and SLA commitments, this should be on your radar.

TypeScript isn't just about typing your code—it's a powerful tool that helps you write safer, more expressive, and maintainable software. Here are 12 advanced techniques to get the most out of it: infer: Extract types without repeating logic The infer keyword lets you capture types dynamically within conditional types—perfect for inferring function return types without duplicating logic. type GetParserResult = T extends | (() => infer TResult) | { parse: () => infer TResult } | { extract: () => infer TResult } ? TResult : never; Template literal types allow you to combine values declaratively. type Bread = "croissant" | "baguette"; type Filling = "cheese" | "ham"; type Option = `${Filling} ${Bread}`; // "cheese croissant" | "ham baguette" | ... You can even customize with …  ( 4 min )

Given that MiniScript is a very minimalistic scripting language, it purposely lacks an Enum type. Its types are Number, String, List, Map, and funcRef (ie. a function reference) -- and that's it. That means that when you want to express an Enum type, you may find yourself using magic numbers. You can use Numbers after all -- in fact I would imagine most underlying Enum implementations do in fact use numerical types under the hood -- but if you find yourself writing code like ship.firingMode = 2, you're probably going to be in for a world of hurt when you try to return to your space shooter game after a six month break. You may not be able to remember the significance, nuances, and intricacies of firing-mode 2 off a quick glance. Alternatively, you can use the String type. ship.firingMode =…  ( 4 min )

As I continue documenting my n8n automation journey, one thing quickly became clear — not every tool you want to automate has a native integration. That’s where one of the most powerful features in n8n comes in: The HTTP Request node.

In simple terms: The HTTP Request node allows your workflow to talk to any external web service through an API. Imagine it like sending a digital letter to another app saying: “Hey! Here’s some info — do something with it and let me know what happened. And best of all, you don't have to write custom code to make it happen. Because not every app you need will be in n8n…  ( 5 min )

If you are writing in Java and need to convert a DTO (data transfer object) to JSON before sending it out, there are libraries that will do this task for you. Jackson is one of them. It’ll use Java reflection to look for getters to figure out what data to write to JSON. Let’s say you have a few of these DTOs and some parts of them overlap, that is they have the same fields in common. You don’t need many overlapping DTOs before you end-up with code duplication that you can’t overcome with inheritance alone. Does it matter? DTOs are just lightweight data containers. There is no business logic in them. What duplication are we talking about? Fine. But a DTO doesn’t have to be just a POJO when it has the potential to be so much more :) For example, it can represent your integration with an acco…  ( 4 min )

"The hottest programming language of the 2020s is English." — Andrej Karpathy Not long ago, Moore's Law amazed us with its promise to double transistors every two years.

TL;DR: Larian Studios originally experimented with a highly stylized, almost cartoony art style for Baldur’s Gate 3, tearing the visuals down and restarting the look at least twice. In a recent AnsweRED podcast appearance, art director Alena Dubrovina explained they toyed with indie-book aesthetics before finally landing on a richer, grounded style reminiscent of Divinity: Original Sin. Why it matters: The team’s rigorous “complete turnarounds” and head-sculpt reworks show just how crucial visual identity was to BG3’s success—and while that realistic approach paid off, Dubrovina hopes one of Larian’s upcoming titles will finally lean into a bolder, cartoon-y vibe.  ( 3 min )

Nintendo’s upcoming Switch 2 is already surfacing in the wild (reportedly in the UAE and even popping up at some US retailers), but early adopters can’t actually play it yet. Every unboxed unit is locked behind a mandatory Day 1 system update—so you’ll need to hook up to the internet (or hope physical games include the patch) before any software — old or new — will boot. With launch day set for June 5, Twitch unboxings and store sightings are just the appetizer. When the console finally goes live it’ll debut alongside first-party hits like Mario Kart World, Switch 2 Welcome Tour and The Legend of Zelda: Tears of the Kingdom, plus a hefty third-party lineup from Cyberpunk 2077 to Street Fighter 6.  ( 3 min )

TL;DR: Bethesda proudly touted 3 million players for DOOM: The Dark Ages, but analytics firm Alinea pegs actual copy sales at just 800 K (200 K on PS5, 200 K on Xbox, 400 K on Steam) with the rest hoofing it through Xbox Game Pass at effectively $12 a pop. Ampere’s data differs—500 K on PS5 and over 2 million on Xbox (mix of purchases and Game Pass)—but everyone agrees sales are underwhelming for an AAA DOOM release. Beyond the eyebrow-raising player-count flex, slow Steam uptake and lukewarm fan sentiment (especially vs. DOOM 2016/Eternal) have reignited the great $70 game-price debate. High entry costs might mean it takes ages to break even, and many are wondering if the whole “industry-standard” price tag needs a serious rethink.  ( 3 min )

Nowadays most developers uses express by default to build a new Node.JS app. It's is popular, easy to use and even Nest.JS uses it behind the scenes. But if you take a look at the Fastify docs, you’ll see that it works quite differently from Express: Fastify uses fast-json-stringify by Matteo Collina with built-in functions based on schemas for serialize objects too fast Fastify uses a radix tree for routing - a compact and optimized tree built during server setup. It’s minimalist, with a strong focus on core performance Native validation using JSON Schema via Ajv Express working as well but for optimization... Express uses JSON.stringify for serialize objects Linear routing based on route definition Minimalist but depends on directly middlewares No native validation Below, you can see two files with simple implementations using Express and Fastify.I also ran a quick benchmark with Autocannon, and here are the results: Express might feel comfortable, but give Fastify a try at least once.

For developers, this opens the door to programmable voice workflows that integrate directly into apps and business logic. Whether you’re building internal tools or customer-facing applications, programmable voice APIs and cloud PBX solutions offer a flexible foundation to handle calls, automate routing, and log interactions with full transparency. Legacy telecom infrastructure has historically been inflexible, expensive, and difficult to integrate. Today’s programmable voice solutions, powered by VoIP PBX platforms, allow developers to: Trigger logic on inbound/outbound calls Record, transcribe, and analyze conversations Route calls dynamically using exte…  ( 4 min )

In Web3, virality isn’t optional — it’s embedded in the architecture. Unlike Web2, where paid ads and influencer campaigns can do the heavy lifting, Web3 projects rely on ecosystems, token incentives, and community-driven growth. And at the center of it all? The humble referral system. But here’s the kicker: most referral programs in crypto… suck. Either they offer weak incentives, are easy to game, or are hidden behind clunky dashboards no one uses. So how do we build referral systems that actually scale in Web3? 🚀 From PayPal to Polygon: Evolution of Referral Systems Web3 tried to replicate that — but ran into friction: On-chain UX is harder Bots and sybil attacks game airdrops Real value takes time, not just clicks So now, we’re seeing a third wave of referral systems: KYC-based rewards, not just address-based Milestone-based tiers (trade volume, time active) Gamified dashboards showing progress and earnings 📊 What Makes a Web3 Referral System Effective? You want a program that scales with usage, not just signups. Referrals should reward engagement — not one-click hype. 🔍 Comparing the Big Players 👉 WhiteBIT stands out for two reasons: 40–50% of trading commissions are shared Emphasis on KYC-complete users = higher LTV Tools like referral QR codes, share links, and invite monitoring make it easy for creators to promote This makes it one of the most creator-friendly options for real growth. 📈 Final Thought: Make It Easy, Make It Real If your product is good, and your referral architecture respects the user… growth will follow.  ( 4 min )

Leapcell: The Best of Serverless Web Hosting In the field of web application development, the Web Server Gateway Interface (WSGI) serves as a standard interface between Python web applications and web servers, playing a crucial role.

JavaScript often feels magical to newcomers and even to seasoned developers at times. Some of that “magic” is powered by concepts like lexical scoping and closures—two foundational principles that give JavaScript its flexibility and strength. Understanding these concepts not only makes you a better developer, but also unlocks the door to writing more elegant, efficient, and bug-free code. In this article, we’ll demystify lexical scoping and closures, demonstrate how they work under the hood, and show you how to harness them like a pro. What is Lexical Scoping? Lexical scoping means that the scope of a variable is determined by its position in the source code—not where or how it's called. When JavaScript compiles your code, it organizes variables into nested scopes based on where they phy…  ( 5 min )

As businesses increasingly move toward cloud-native infrastructure, voice communication systems have evolved from traditional hardware PBX systems to flexible, scalable, and programmable VoIP PBX solutions. For developers, this shift unlocks a range of possibilities to integrate real-time communications directly into their apps, services, and workflows. In this article, we’ll break down what a VoIP PBX is, explore its programmability, and walk through how to integrate a cloud VoIP system using APIs. What Is a VoIP PBX? Remote access from any device Lower maintenance overhead API-level integration with CRMs, helpdesk systems, and internal tools Scalability with user demand Popular providers like Ringover, Twilio, and 3CX offer programmable VoIP PBX platforms that developers can tap into. Why Developers Should Care This opens up a range of use cases: Route calls based on CRM data Log call metadata in real time Analyze call quality with monitoring APIs Trigger automations (e.g., Slack alerts) based on call events Real-World Example: Call Logging with Webhooks js // index.js const app = express(); const db = new Client({ app.post("/call-webhook", async (req, res) => { try { app.listen(3000, () => console.log("Webhook server listening on port 3000")); Once this endpoint is exposed (e.g., using ngrok or deployed to a server), you can register it with your VoIP provider’s webhook settings. Leveraging AI and Analytics Example use cases include: Triggering ticket creation from key phrases Sentiment analysis on support calls Keyword-based call tagging Final Thoughts Have you worked with programmable voice systems or built something cool with a VoIP PBX? Let’s connect in the comments 👇 Let me know if you'd like it tailored to a specific provider (like Ringover, Twilio, etc.) or focused more on front-end, back-end, or DevOps perspectives.  ( 4 min )

I’m not going to lie to you, working with Webflow was something I wasn't expecting to do when I first started. When I joined Skyrocket Digital as a contractor back in the pandemic arc of the world, I thought most of my work was going to be writing code to develop front and back end; And for a while it was, but that was not the only project I was working on with them.

Streamlining LLM Integration: Building a JavaScript MCP Server for Hacker News Integrating LLMs into real products still feels messier than it should be. Instead of clean patterns or shared infrastructure, most devs end up hacking together one-off code to connect models with APIs, databases, or business logic - none of it reusable, scalable, or easy to maintain. The Model Context Protocol (MCP) aims to fix that. It's a minimal, open standard from Anthropic. It provides a unified way for exposing tools, data, and prompts to language models in a structured, predictable way. Instead of building a new integration layer for every app or agent, MCP gives you a common interface - and it already works with applications like Claude Desktop, Cursor, and Windsurf.

By now, most developers are familiar with Generative AI, the kind that writes text, generates code, creates images, or summarizes data. It’s powerful, but it’s also... reactive. You give it a prompt, it gives you a result. End of story. But lately, there’s a new player making waves: Agentic AI. And it’s not just a buzzword. Here’s the key difference: Generative AI creates content or suggestions when asked. Agentic AI goes further — it takes initiative, makes decisions, and executes tasks autonomously. Let’s say your AI detects low inventory. A generative model might say: “You’re running low on product X.” It’s the difference between assistance and action. We explained this in a recent conversation: Agentic AI vs Generative AI Explained Simply If you’re building AI apps or exploring automation in your projects, this shift from suggestion to execution could be a game-changer. Curious to hear from you! Where do you see Agentic AI making the biggest impact? 🤔  ( 3 min )

If you're building a SaaS product, chances are you've signed up for Stripe, added a checkout form, and started charging customers.

NVIDIA has just announced native support for Python in its CUDA platform, marking a major shift in how developers can access GPU acceleration. For the first time, Python developers can write CUDA programs without needing to rely on C or C++ bindings. This native integration drastically lowers the barrier for using GPUs in scientific computing, AI, and data-heavy Python applications. The new cuda-python package gives direct access to CUDA’s driver and runtime APIs, letting users launch kernels, manage memory, and control streams entirely from Python. It also includes support for just-in-time (JIT) compilation, which means you can write dynamic GPU code directly in Python, compile it on the fly, and run it immediately. A key innovation is the new CuTile programming model, which brings a tile-based structure to CUDA operations. CuTile is designed to feel natural to Python users familiar with NumPy and CuPy, and it allows for efficient manipulation of large data arrays without needing to manage threads manually. This move brings CUDA closer to Python’s ecosystem and could reshape how GPU computing is taught, deployed, and scaled across AI and HPC workloads.

Originally published on patangrid.site I kept seeing mentions of Opera Neon 2025 pop up — waitlists, AI buzz, and people calling it an AI-powered browser. My first reaction? “Another browser? Why switch from Chrome?” But once I realized this was an experimental browser from Opera testing out agent-like AI features, I figured it was worth a look. I found the official info on Opera’s site. If you're trying to download Opera Neon, don’t get too excited — it's invite-only for now. Opera’s been building browsers since the ’90s, but this might be their most ambitious idea yet. The previews show a minimalist design and AI baked right in. It looks... different — in a good way. The Opera Neon UI looks like it was designed to end tab chaos. You get visual tabs that show a preview of each page, which makes jumping between websites feel more intuitive than just staring at a bunch of favicons. There’s also a floating sidebar that holds key tools like bookmarks, workspace controls, and the AI assistant — all tucked neatly to the side without taking up valuable screen real estate. And that’s just scratching the surface. Want to know how Opera Neon uses AI to organize your tabs, issue distraction warnings, and even make activity-based suggestions?

** ** Artificial Intelligence is rapidly reshaping the global job market. While AI promises innovation and efficiency, it also presents significant challenges that require urgent attention. Up to 50% of entry-level white-collar jobs risk displacement due to automation, with unemployment potentially rising to 20%, a rate not seen since the Great Depression (Anthropic CEO Dario Amod). Currently, 14% of the global workforce—approximately 375 million workers—have been affected by AI through job losses or career changes, with around 5 million jobs lost worldwide. The most impacted sectors include customer service (1.2 million jobs lost), IT services (850,000), warehousing and logistics (1.1 million), administrative and clerical roles (750,000), banking (400,000), and retail (300,000). Women’s jobs are disproportionately vulnerable, with 41% of female roles at risk compared to 28% for men, reflecting the higher concentration of women in automatable sectors. Attempts by companies like Clara and IBM to fully replace human roles with AI have demonstrated the limitations of automation, highlighting the continued importance of human skills. Looking ahead, by 2026, AI is projected to displace 75 million jobs globally but create 133 million new jobs, emphasizing a shift toward roles requiring new and different skills. This transition risks exacerbating inequality, favoring those with greater education and resources, and posing a challenge for inclusive economic growth. The path forward requires coordinated action: Accelerated workforce retraining and upskilling programs Thoughtful regulation of AI adoption Strategic planning to ensure equitable opportunities in the evolving job market As AI continues to evolve, organizations and governments must collaborate to create a future of work that balances innovation with inclusivity and social responsibility. How is your organization preparing for the impact of AI on jobs?  ( 3 min )

As there's no single right way to implement GitOps, it can be tricky to work out which tools will deliver the best results for your team. In this article, we'll look at seven options that should be on your radar in 2025. GitOps is a methodology for software development and infrastructure management that positions Git repositories as your workflow's single source of truth. Instead of manually running commands to apply changes, GitOps revolves around declarative config files that are versioned in your repositories. CI/CD-driven tooling then consumes the files to automatically create and update your resources. Here's the GitOps workflow in a nutshell: GitOps increases development velocity while guarding against the mistakes that can occur when DevOps teams directly interact with infrastructu…  ( 8 min )

No artigo de hoje, vamos falar sobre uma prática da qual eu já fui vítima, e você, leitor, provavelmente também já foi (ou ainda está sendo). Trata-se da famigerada prática de criar endpoints excessivamente verbosos. Quando estamos desenvolvendo uma API REST para nosso sistema, é comum tentarmos facilitar o acesso a dados muito específicos. No entanto, isso muitas vezes se transforma em uma bola de neve. Quem nunca se pegou pensando: “Só mais um endpoint e tudo estará resolvido”... e repetiu isso incontáveis vezes? Isso acontece porque ignoramos um fator muito importante no conceito de API: ela deve servir como um portal de acesso aos recursos gerais do sistema, e não como um grande servidor repleto de rotas altamente específicas para cada situação. Esse problema costuma surgir, principalmente, quando lidamos com recursos que estão relacionados entre si. Pense na seguinte situação: Você precisa listar usuários que possuem tarefas atribuídas. A abordagem comum e tentadora é criar um endpoint como: /getUsersWithTasks Mas esse tipo de design fere princípios fundamentais de uma API bem construída. Em vez disso, pense na sua API como uma interface para recursos, e usuários são um recurso. Logo, uma forma mais adequada e escalável seria algo como: /users?withTasks=true Esse formato segue o padrão REST, é mais flexível e permite expandir facilmente os filtros no futuro, como: /users?withTasks=true&active=true Evite criar endpoints com verbos como get, delete ou create. Além de quebrar os princípios REST, isso torna sua API redundante e desnecessariamente verbosa. Por exemplo: 🚫 /getUserById Além disso: Prefira filtros via query parameters em vez de encher a URL com parâmetros. Mantenha seus endpoints focados em recursos, não em ações. Seguindo essas dicas simples, sua API se tornará muito mais limpa, intuitiva, escalável e fácil de manter.  ( 3 min )

I realised that many companies offer no-code platforms to their users for automating workflows. I spent a week deep-diving into Gumloop and other no-code platforms. agents. They're built for workflows. There's a difference. Agents need customisation. They have to make decisions, route dynamically, and handle complex tool orchestration. Most platforms treat these as afterthoughts. I wanted to fix that. Although it's not production-ready and nowhere close to handling the requests of companies like Gumloop and similar ones, this is intended to showcase the robustness of Vibe coding and how easily you can build sophisticated apps in a matter of days. You can also carry forward the work to improve it. NextJS was the obvious choice for the vibe-coding stack. Could I have used FastAPI with a Re…  ( 7 min )

🚀 How HashMap Works Internally in Java? 🧐 Key Concepts of HashMap: Stores data as key-value pairs 🗂️ (key -> value) Uses Hashing to find data quickly ⚡ Allows one null key and multiple null values 🤔 Does NOT maintain order (Unlike LinkedHashMap) 🔀 Handles collisions using Linked Lists or Trees 🌳 🔍 How HashMap Works Internally? Calculate the hash of the key using hashCode(). 🔢 Find the bucket (index) using (hashCode % table size). 🗄️ Store the key-value pair in the bucket. ✅ If two keys have the same hash (collision), store them in a linked list (before Java 8) or a balanced tree (after Java 8). 🌲 Example: import java.util.HashMap; public class HashMapExample { public static void main(String[] args) { HashMap map = new HashMap(); map.put(1, "Apple"); map.put(2, "Banana"); map.put(3, "Cherry"); map.put(1, "Avocado"); // Replaces "Apple" because keys are unique! System.out.println(map); // Output: {1=Avocado, 2=Banana, 3=Cherry} } } ✅ Only one value per key..!!! If a key already exists, the old value is replaced. 🔥 Visualization of HashMap Storage: If you insert another "1 -> Avocado", it replaces "1 -> Apple" because keys must be unique. 🚀 How Does HashMap Handle Collisions? Before Java 8 → Uses a Linked List Java 8 and later → Uses a Balanced Tree (Red-Black Tree) when collisions become high (threshold = 8). 🔥 Summary HashMap stores key-value pairs and finds them fast using hashing. Uses hashCode() to compute an index (bucket). Handles collisions using Linked List (before Java 8) or Tree (after Java 8). Keys must be unique; if a key exists, its value is replaced.  ( 4 min )

If you've been following along with this series you may have noticed that the components we have created so far all suffer from an issue known as FOUC which stands for Flash of Unstyled Content. This happens because—just like any scripts that manipulate the DOM—the custom element definitions we have created so far have to come after the content has been parsed in order to work with that content. As a result, when the DOM is parsed our custom tags are initially treated as generic HTML elements and rendered without any of the structure or styles defined in our Shadow DOM being applied. Today we will discuss ways to avoid this issue. The simplest way to prevent our elements from appearing before they are registered is by hiding them with CSS. We can add the following rule to our host document…  ( 7 min )

Google, founded in 1998 by Larry Page and Sergey Brin while they were Ph.D. students at Stanford University, has become one of the most influential technology companies in history. Originally launched as a search engine, Google transformed how people access and interact with information online. At the heart of Google's success is its powerful search algorithm, which ranks web pages based on relevance and authority. This innovation not only made Google the go-to search engine globally but also revolutionized the digital marketing industry through platforms like Google Ads and Google Analytics. Over the years, Google expanded far beyond search. It developed the Android operating system, now the most widely used mobile OS, acquired YouTube to dominate online video, and introduced Gmail, Google Maps, Chrome, and the Google Workspace suite. Each of these tools became a cornerstone of modern digital life. The company’s parent organization, Alphabet Inc., was created in 2015 to oversee a broader range of ventures, including artificial intelligence (DeepMind), autonomous vehicles (Waymo), and life sciences (Verily). Google continues to lead in AI, with products like Google Assistant and its recent work on generative AI models. However, Google's dominance has also sparked concerns over privacy, market monopoly, and data ethics. Antitrust lawsuits in the U.S. and abroad highlight the tension between innovation and regulation in the digital era. Today, Google remains a symbol of innovation and connectivity, shaping how billions of people learn, communicate, and do business. Whether it’s through search, cloud computing, or AI, Google's impact on the modern world is profound and enduring.  ( 3 min )

Coming from React, switching to Vue feels like moving from a toolkit to a lifestyle. In React, you build your own world. In Vue, the world is already built—it just hands you the keys. I didn’t expect to like Vue. I thought it would feel like jQuery-in-a-Component™—useful, sure, but inelegant. What I found instead was a different mental model, a developer experience centered around clarity over control, and a stack that didn’t just work—it felt like it wanted to work. So far, we have covered some basic building blocks of Vue, now let’s walk through how to think in Vue. In React, you think in functions.

At its core, UEBA is a security approach that examines the behavior of both users (employees, contractors) and entities (devices, servers, applications) in your network. It uses analytics and machine learning to recognize routine activity, then identifies anomalies that could indicate a threat. These could include unexpected logins, large data transfers, or system access at odd hours. Instead of following static security rules, UEBA adjusts dynamically. It connects various data points across your environment, helping security teams understand when something suspicious may be occurring, even if it appears harmless in isolation. Legacy security solutions are typically reactive and rule-driven. They are effective against known threats but often miss new or subtle ones. UEBA fills this gap by …  ( 4 min )

Picture this: You're building an application where users upload important kyc documents—driver's licenses, bank statements, tax documents. Everything seems to work perfectly during testing. Files upload fine, they're stored securely in S3, and when you download them through your admin panel, they open without issues. Then the support tickets start rolling…  ( 6 min )

These days, the hype around vibe coding feels limitless. Tools that promise to turn your ideas into apps with nothing more than a chat prompt are everywhere. But back in March this year, I came across a tweet from a developer who discovered that one of those tools, Lovable, was exposing a user's Supabase API key. While it was a publishable API key, it had no permissions or restrictions, and the developer was able to access all the app's data without authentication, just by looking at the public build. This is not innovation. This is a security breach waiting to happen. This is what happens when people lean too hard on the vibe. They build software by instinct, skip fundamentals, and trust that the tool knows best. But when you are shipping products that handle real data, real users, and r…  ( 6 min )

Accessible Angular Forms are essential to ensure that all our users – including those with disabilities – can interact with our Angular App effectively. By implementing forms with Accessibility (A11y) in mind, we meet legal (EAA 2025 ♿) and ethical standards, and create a more inclusive experience. Accessible forms work better with screen readers, keyboard navigation, and assistive technologies – which not only helps users with impairments but also enhances the overall UX of our Angular Apps. In Angular, we have two types of forms: Template-driven Forms: These are simpler and more declarative, relying on Angular Directives to create forms. They are built around the NgModel directive and generally used for simple forms. As the name suggests, these are implemented in the template through att…  ( 7 min )

Potential customers often arrive at your pricing page during the final stage of their journey. By this point, they’re likely already interested in your offering and are evaluating pricing models before making a purchase decision.  That’s why your pricing page layout plays a critical role in communicating your plans and guiding users toward the right plan for their needs. But what exactly makes a SaaS pricing page effective? Interestingly, most SaaS pricing pages tend to follow a similar structure. This isn’t by accident, which is explained by Jakob’s Law: Users prefer familiar experiences. When your pricing page resembles layouts they’ve seen before, it builds trust and reduces friction. Deviating too much from these expectations can actually hurt your chances of conversion. In this blog, …  ( 7 min )

In the past few years, AI has taken a front seat in how we work, build, and even learn. While that’s exciting in many ways, there’s something no one is really talking about — the quiet decline of true learning, especially in the programming world. As someone who's learning and building daily, I've noticed a shift that worries me. Here’s what’s going on. Let’s say AI takes over most software jobs. That fear alone is already discouraging a lot of beginners. They wonder: “Why should I learn to code if AI can already do it better and faster?” The result? Fewer people are even trying to learn. And among those who do, many quit early. Not because they’re lazy — but because the beginning is genuinely hard. Most people don’t realize that learning to code takes time, patience, and frustration.

Retrospectives generate valuable team insights, but those insights often get stuck in the tool where they were created. Your team discusses important improvements, identifies action items, and reaches consensus on priorities - then someone has to manually recreate everything in Confluence for documentation. Most teams face the same challenge: retrospective insights need to live in Confluence for stakeholder updates, team reference, and organizational knowledge - but manual recreation is time-consuming and details get lost. Kollabe's new Confluence integration transforms completed retrospectives into comprehensive Confluence pages with a single click. Complete retrospective summary: All items, discussions, and outcomes Professional formatting: Clean, readable layouts that preserve context Action items highlighted: Key takeaways prominently displayed Voting data preserved: Team consensus and priority rankings maintained Choose exactly where your documentation goes: Select specific Confluence space Pick exact page hierarchy location Integrate with existing documentation structure Maintain organizational consistency Retrospective insights become permanent, searchable team knowledge instead of isolated session records. Teams can: Reference past improvements when similar issues arise Track improvement themes across multiple sprints Share outcomes with stakeholders easily Build organizational memory that survives team changes The setup is straightforward: Connect your Confluence account via OAuth Select your target space and page location Click export after your retrospective Access formatted documentation immediately This feature is available for all Kollabe users. Turn your retrospective insights into lasting team documentation that stakeholders can access and teams can reference for continuous improvement.

Introduction This article is a continuation of Expose home server with Rathole tunnel and Traefik article, which explains how to permanently host websites from home by bypassing CGNAT. That setup works well for exposing a single home server (like a Raspberry Pi, server PC, or virtual machine), but it has a limitation: it requires one VPS (or at least one public network interface) per home server. This is because the Rathole server exclusively uses ports 80 and 443. But it doesn't have to be like this. We can reuse a single Rathole server for many tunnels and home servers, we just need a tool to load balance their traffic, as long as our VPS's network interface provides enough bandwidth for our websites and services. This article explains how to achieve that using Traefik HTTP and TCP rou…  ( 8 min )

Why Encoding? tokenization. In Natural Language Processing (NLP), we use TensorFlow's Keras API **to easily convert text into sequences of numbers using a **Tokenizer. Why use tensorflow.keras? For smoother experience, especially when using TensorFlow, tools like Google Colab are recommended to avoid installation issues. 1. Tokenisation Explanation: tok=tokenizer() it is an initialisation of tokeniser which will break sentence into words. corp, corpus or paragraph which we will break it. tok.fit_on_texts(corp), it will give index to words. How indexing works in here? the most frequent word get lowest index like 1. print(tok.word_index), it ask for what is word index. 2. Convert text to sequences Problem: What Happens with New Words? When you train a tokenizer on some text, it only builds a vocabulary from those words. Example Without OOV Handling we tokenised the text into word and it have assigned the index. Now try a sentence with a new word "black": Now we have add word black texts_to_sequences() skip the word black. Handle OOV (Out-of-Vocabulary) Words Out of vocabulary words is word that is not present during training fit_on_texts(). Output: {'balck': 1, 'i': 2, 'need': 3, 'coffe': 4, 'we': 5, 'can': 6, 'make': 7, 'it': 8, 'from': 9, 'water': 10} Even though "black" wasn’t in training, it gets index 1 — the reserved OOV token. Limiting the number of words. Let say I don't want whole paragraph I want to limit the words why? because of efficiency if I take corpora (whole paragraph) then to process it will take time. To make it easy we will limit it. tok=Tokenizer(oov_token='balck',num_word=4)  ( 4 min )

"Everyone starts somewhere. I started with confusion, Google searches, and a lot of coffee." But one day, I found the Namaste JavaScript series by Akshay Saini. And that’s when things started to click. He didn’t just teach—he explained why, in a way that felt like a friend walking me through it all. That’s when I decided to dive into Namaste React and Namaste Node.js. ⚛️ Namaste React – Building UIs, Building Confidence But lesson by lesson, project by project, I started seeing it: I built my first component. Then another. I passed props like a pro. I even figured out hooks (well... eventually 😅). There were moments of frustration, but also a lot of "Wow, I actually made that!" And that feeling? Pure gold. 🌐 Namaste Node.js – From Frontend to Full Stack Let me be real: backend scared me. Servers, requests, APIs—it sounded too technical. But this series? It made the complex feel simple. I learned: How servers actually work Building REST APIs from scratch Routing, middleware, and even a bit of MongoDB I started building full-stack apps. Not huge ones, but they were mine. And they worked. ❤️ What I Learned Beyond Code It taught me: To be patient with myself To Google like a ninja That everyone starts as a beginner And that the “hero” isn’t someone who knows everything, but someone who doesn’t stop learning 🚀 To Anyone Starting Now...

I’ve been exploring an idea for a fully automated AI-powered cryptocurrency trading system that could be built entirely using free and publicly available services. The concept combines Groq AI for ultra-fast decision-making, a free crypto news API to analyze real-time market sentiment, and exchange APIs like Binance’s to execute live trades and monitor balances. The system would automatically analyze trends, interpret news, and make informed trading decisions in real time. It would also include a web-based dashboard to display capital status, trade logs, AI insights, and profit and loss — all updated live for full transparency. The goal is to create a highly efficient, intelligent, and low-cost crypto trading setup using freely accessible tools and APIs. It’s still just an idea at this stage, but I believe it has strong potential.

What is a coroutine object? A coroutine is a special kind of function that can pause and resume its execution, allowing asynchronous programming. When you call an async function, it doesn’t run immediately like a regular function. Instead, it returns a coroutine object — essentially a “promise” that it will run when awaited. async def say_hello(): print("Hello!") return "Done" result = say_hello() # This returns a coroutine object, it does NOT execute yet print(result) # # To actually run the coroutine and get the result, you need to await it: output = await say_hello() # Now it runs, prints "Hello!" and returns "Done" print(output) # "Done" Coroutine objects represent tasks that haven’t run yet. You must await them inside an async function to actually execute the code and get the result. If you don’t await and just return the coroutine, it’s like returning a “recipe” instead of the “finished dish.” Your repository functions are async (return coroutine objects). If you return the coroutine itself (without await), FastAPI tries to serialize the coroutine object, which causes errors. You must await those async calls so FastAPI gets the actual data to send in the response. Term Meaning coroutine function A function defined with async def coroutine object The result of calling a coroutine function — a "lazy" task not yet run await The keyword that runs the coroutine and gets its result  ( 3 min )

Overview, Historical Timeline, Problems & Solutions In Python, all data is made of objects. A number is an object. A string is an object. A list is an object. Even functions and classes are objects. Python treats everything as an object so it can store, copy, or link all parts of a program. When you run a program, you give Python values. Python turns those values into objects. The object holds data and also knows what it can do. This is what makes Python flexible and powerful. Python lets you represent all data as objects. name = "Ada" age = 36 Each value here becomes an object. The word name points to a string object. The word age points to a number object. Every object in Python has three parts: identity, type, and value. The identity is like a tag number. It never changes. The type …  ( 7 min )

Kubernetes is a powerful system—but with great power comes great responsibility. As clusters grow and more users or services interact with them, access control becomes a critical aspect of your security posture. This is where RBAC (Role-Based Access Control) comes into play. In this article, we’ll demystify Kubernetes RBAC, explain how it works, and walk through practical examples to help you implement it effectively. What Is RBAC in Kubernetes? Grant read-only, read-write, or admin access to specific resources. Limit users or services to namespaces or cluster-wide resources. Enforce the principle of least privilege. RBAC Key Components Role:-Defines a set of permissions within a namespace. ClusterRole: Like Role, but applicable cluster-wide. RoleBinding: Grants a Role to a user/service ac…  ( 4 min )

There’s something strangely poetic about failing 147 times in a row… and still pressing “retry.” That’s Flappy Bird for you — a game that feels like an inside joke between coders and chaos. But instead of just flapping endlessly and rage-quitting like most of us did in 2013, I decided to take a different route: analyze the game using Python. Because sometimes, understanding the monster is the only way to tame it. Why Flappy Bird Still Holds Our Attention As a Python dev, I couldn’t help but think: What if we could quantify the chaos? What if we could understand the rhythm of those pipes, the bird’s flight physics, or the hitbox sensitivity — all through code? Using Python to Analyze Gameplay Data Success rate per session And let me tell you — once I plotted my own “death heatmap,” I realiz…  ( 5 min )

Tired of 403s and blank pages when scraping JavaScript-heavy websites? Looking for one library which can take care of 403, js rendering automatically? You're not alone — and that's exactly why I built ScrapeSome. ScrapeSome is a developer-friendly Python library that makes scraping modern websites simple — even the ones loaded with dynamic JavaScript or tough anti-bot protections. It’s fast, lightweight, and requires zero boilerplate. I kept hitting walls on scraping projects: Pages rendered everything with JavaScript APIs were locked down or undocumented requests/Scrapy failed or got 403 error Setting up full browser automation felt too heavy for small jobs So I built ScrapeSome — to fill the gap between requests and full-on headless scraping frameworks. Handles both static and JS-heavy …  ( 5 min )

When I started learning the Java basics. One of the first things I came across was data types. it’s very important. Let me share what I understood so far. Data Types: Java has two main types of data types: Primitive Data Types. In this post I will give the outline Primitive Data Types. There are 8 Primitive Data Types: byte | 1 byte | Small whole numbers | byte a = 10; | short | 2 bytes | Bit bigger numbers | short b = 1000; | int | 4 bytes | Most common whole numbers | int age = 25; | long | 8 bytes | Huge whole numbers | long stars = 123456789L; | float | 4 bytes | Decimal numbers | float price = 12.5f; | double | 8 bytes | More accurate decimals | double pi = 3.14159; | char | 2 bytes | Single character | char letter = 'A'; | boolean | 1 bit | True or False | boolean isJavaFun = true; | My Personal Suggesion: First start with int for numbers and double for decimals.  ( 3 min )

How to Speak Up and Get Promoted in an IT Company While every company operates differently, the overall mechanics of career growth and salary increases in the IT industry tend to follow similar patterns. At some point, almost every professional — from junior developers to seasoned tech leads — faces the same question: How do I speak up and get recognized if I want to grow or earn more? To move forward successfully, it's important to understand not only your personal goals but also the company's motivations. When a company opens a new position, the primary goal is usually the same: improve business efficiency and profitability. Common reasons include: Filling a specific team role. Increasing team productivity and delivery speed. Reducing pressure on key individuals. Improving product q…  ( 5 min )

When you install or run Python-based tools on Arch Linux — especially from the AUR — you might notice that your system accumulates a lot of __pycache__ directories. These are generated when Python byte-compiles modules, but they aren’t always removed when you uninstall a package. In this short guide, we’ll walk through how to identify and optionally clean up those __pycache__ directories — specifically the ones not owned by any package — and exclude system paths like Flatpak while we're at it. Tools installed via the AUR (like waydroid-scripts-git, for example) might drop files under /opt, /usr/local, or other places. These files (especially .py and __pycache__) might not be tracked by pacman, so even after uninstalling the tool, leftover Python cache directories can remain. __pycache__ Directories Here’s a one-liner that will: Search your system for all __pycache__ directories Skip the Flatpak directory (/var/lib/flatpak) Check whether each is owned by any package Print only the ones that are not owned find / -type d -name '__pycache__' -not -path '/var/lib/flatpak/*' 2>/dev/null | while read dir; do pacman -Qo "$dir" &>/dev/null || echo "Not owned: $dir" done Not owned: /opt/waydroid-scripts/tools/__pycache__ Not owned: /usr/local/lib/python3.11/site-packages/some_tool/__pycache__ __pycache__ directories aren't dangerous, but they can accumulate and clutter your system — especially in directories that aren’t cleaned by package managers. With a few commands, you can find and clean up these leftovers safely, keeping your system neat and under control. Have your own cleanup tricks? Share them in the comments!  ( 3 min )

Introduction Force-pushing in Git (git push --force) is a powerful but dangerous command. It overwrites remote changes without checking if others have pushed new commits, which can lead to lost work. Fortunately, Git provides a safer alternative: git push --force-with-lease. This command ensures you don't accidentally overwrite someone else's changes while still allowing you to rewrite history when needed. In this guide, we'll explore how --force-with-lease works, when to use it, and best practices for avoiding mistakes. --force-with-lease Works Unlike --force, which blindly overwrites the remote branch, --force-with-lease checks if the remote branch has changed since you last fetched it. git push --force → Overwrites remote branch no matter what. git push --force-with-lease → Only o…  ( 6 min )

One of the most powerful features of cloud computing is scalability—and Microsoft Azure makes it incredibly simple with Autoscaling. Whether you're hosting a small web app or a full-scale enterprise platform, you don’t want to be manually adjusting resources every time traffic spikes. That’s where Azure’s autoscaling steps in. Autoscaling means your application can automatically increase or decrease resources based on demand. Instead of overprovisioning (and overpaying) or dealing with performance issues during traffic spikes, you set rules that let Azure do the scaling for you. Azure supports autoscaling for several services: App Services Virtual Machine Scale Sets Azure Kubernetes Service (AKS) Azure Functions In this guide, we’ll focus on App Service autoscaling, since it’s one o…  ( 4 min )

JavaScript’s type coercion and dynamic typing system are full of subtle (and sometimes surprising) behaviors. Understanding these quirks can make you much more confident and effective as a JS developer. Here’s a list of not-so-obvious JavaScript type coercion examples, grouped into categories with explanations: 1. String vs Number Comparison Expression Value Reason '10' < '2' true Lexicographic comparison: '1' comes before '2' '10' < 2 false string '10' is coerced to number 10 '5' == 5 true string '5' is coerced to number 5 '5' === 5 false strict equality, no type coercion Rule: Loose equality (==) allows type coercion. Strict equality (===) does not. 2. Falsy Values JavaScript has falsy values that act like false i…  ( 4 min )

Smart contracts are the backbone of decentralized applications (dApps) on the Ethereum blockchain. These contracts are written in Solidity, a statically typed, contract-oriented programming language tailored for Ethereum. One critical yet often overlooked aspect of smart contract development is how contracts are initialized when deployed to the blockchain. This blog post offers a deep dive into the concept of constructors in Solidity, how they work, their purpose, and best practices to keep your contracts secure and efficient. A constructor is a special function in a Solidity contract that is executed only once, at the moment the contract is deployed. Think of it as the setup phase of your smart contract—this is where you define the initial state, set permissions, or configure parameters t…  ( 5 min )

It’s Always the Refund It started, as these things always do, with a Slack message from support that began: "This is probably nothing, but…" It never is. Turns out a customer had requested a refund for a $0 order—paid entirely with a promotional code that someone in marketing named “YOLO100.” Our system, ever obedient, generated a pristine digital refund for exactly zero currency units and confidently shoved it into the payment gateway, which replied with the transactional equivalent of a raised eyebrow: "Invalid amount." From there, the trail of confusion expanded outward like a suburban sprawl. Engineering said it shouldn’t be possible. QA said it wasn’t in the test cases. Product said it was “an edge case.” (They always say that, don’t they? Every single cliff we fall off was once c…  ( 6 min )

Why RWAs aren’t the decentralized revolution you think they are Tokenized real-world assets (RWAs) are the new crypto darling. Everyone’s hyped: BlackRock’s onchain, treasuries are getting wrapped, and traditional finance is flirting hard with blockchain. But let’s not get it twisted: RWAs aren’t decentralization. They’re TradFi in a blockchain costume. Here’s the inconvenient truth: Want to buy tokenized real estate? Great. But that token doesn’t give you squat unless a legal entity off-chain honors it. Treasury tokens? Same thing. You’re trusting a fund manager, custodian, or regulatory body to redeem it. It’s not trustless. It’s regulatory theater with a smart contract backend. RWAs are less about empowering users and more about navigating global compliance. It’s not about breaking the system. It’s about bending the rules just enough to extract value while pretending to be futuristic. This isn’t DeFi. It’s just TradFi with faster accounting. Let’s be honest: most RWA projects don’t need a blockchain. They use it for: Token issuance Cap table management Tracking asset flow But these are things spreadsheets and CRMs have done for decades. Putting it onchain doesn’t make it revolutionary — it just makes it buzzword-compliant. Web3 wasn’t about rehypothecating bonds or making banks more efficient. It was about disintermediation. Cutting out the middlemen. Giving power back to users. Trustless systems. RWAs? They reintroduce the middlemen — they just wear hoodies now. Tokenized RWAs sound sexy, but they’re just Wall Street playing dress-up in Web3. Until these assets are truly decentralized — not just onchain — they’ll remain more TradFi than DeFi.  ( 3 min )

Instructions: Create a function finalGrade, which calculates the final grade of a student depending on two parameters: a grade for the exam and a number of completed projects. This function should take two arguments: exam - grade for exam (from 0 to 100); projects - number of completed projects (from 0 and above); This function should return a number (final grade). There are four types of final grades: 100, if a grade for the exam is more than 90 or if a number of completed projects more than 10. Examples(Inputs-->Output): 85, 5 --> 90 55, 3 --> 75 55, 0 --> 0 Thoughts: 1.I use the if/else statement to determine the return of the final grade function of different conditions.

Primeiro, vamos com calma Antes de tudo, vamos com calma. Sei que esse tipo de afirmação pode gerar problemas de entendimento e até certo favoritismo em relação a tecnologias. Entretanto, precisamos ter em mente as necessidades que nossas ferramentas suprem e por que devemos usá-las. Nos primórdios do desenvolvimento web, quando queríamos conectar e criar ferramentas, não existiam conceitos como micro-frontends, SaaS, microservices ou nada parecido. O mais próximo disso eram aplicações monolíticas, desenvolvidas com stacks que seguiam arquiteturas “quadradas” e bem estabelecidas. Um exemplo clássico é a infame stack LAMP: Linux Apache MySQL PHP Nessa época, era comum seguir a arquitetura MVC (Model-View-Controller), onde: A View apresentava os dados e recebia as entradas dos usuários; O …  ( 5 min )

Hello, fellow Rustaceans (or aspiring ones)!Welcome back to Week 2 of my deep dive into the Rust programming language, and this week I explored compound types and control flow. Here's what I learned, where I got stuck, and how I'm making it make sense. Here's what I tackled: - A. Compound Types: String (and its relationship with &str) Arrays Slices Tuples Structs Enums - B. Control Flow: if/else if/else loop while for loops with iterators Let's dive into how these building blocks are starting to click for me, and how AI is continuing to be a valuable co-pilot. Last week, we dealt with simple numbers and booleans. This week was all about grouping related data and defining my own custom types.

Preventing direct administrative SSH access is a vital component of any defense-in-depth strategy. In this guide, we’ll explore how to restrict privileged users from logging in via SSH using SELinux’s ssh_sysadm_login boolean. This ensures that administrative access is only available after connecting through a restricted, non-privileged jump account — a critical safeguard against misconfiguration and privilege abuse. Overview: Why Restrict Admin SSH Access Step 1: Ensure SELinux is in Enforcing Mode Step 2: Associate Admin Users with sysadm_u Step 3: Disable ssh_sysadm_login Why Not Just Use sshd_config Final Thoughts & Additional Hardening Tips In Part 1 of this series, we set up a restricted jump user — a non-privileged account used to SSH into a Linux server. This user can then escal…  ( 5 min )

135. Candy Difficulty: Hard Topics: Array, Greedy There are n children standing in a line. Each child is assigned a rating value given in the integer array ratings. You are giving candies to these children subjected to the following requirements: Each child must have at least one candy. Children with a higher rating get more candies than their neighbors. Return the minimum number of candies you need to have to distribute the candies to the children. Example 1: Input: ratings = [1,0,2] Output: 5 Explanation: You can allocate to the first, second and third child with 2, 1, 2 candies respectively. Example 2: Input: ratings = [1,2,2] Output: 4 Explanation: You can allocate to the first, second and third child with 1, 2, 1 candies respectively.

AI-Powered Code Generation From Design Streamlining Design-to-Code Conversion AI tools are really changing how we build things, especially when it comes to turning design mockups into actual working code. It used to be that developers would spend a ton of time just translating what a designer made into code. Now, AI can take those designs and spit out production-ready code in a fraction of the time. This means projects can move a lot faster, and teams aren't stuck in that slow back-and-forth process. It's like having a super-fast assistant that understands design and can write code. This shift lets developers focus on more complex problems instead of repetitive coding tasks. It's a big deal for getting products out the door quicker. The whole idea is to cut down on the manual work involved…  ( 7 min )

What is Binary Search Imagine you are playing a game where you try to guess a secret number from 1 to 10, and you have infinite attempts. You can choose random numbers (without repetition)—maybe you will get lucky and guess it on the first try, or it might take you all 10 tries to reach it. Or you can try counting all the numbers in order—1, 2, 3, 4…—this will still take 10 guesses max, but in a more systematic way. But what if you had to guess a number from 1 to 1000, or even 1 to a million? What about 1 to 10²⁰? As the range increases, brute force becomes impractical. Computer scientists faced the same problem: how do you efficiently find something in a huge range? One commonly used solution is binary search. Binary search works by dividing the range in half with each guess, determinin…  ( 4 min )

🚀 Introduction Queues are everywhere — from the print job waiting on your computer to the request processing system of a large-scale web server. But understanding queues isn’t just about putting items in and taking them out — it’s about knowing what kind of queue to use and when. In this post, we’ll explore: ✅ Different types of queues Whether you’re prepping for interviews, building scalable backends, or just exploring Python data structures, this guide is for you. 📦 What is a Queue? A queue is a First-In-First-Out (FIFO) data structure — like a line at the bank. The first person to arrive is the first to be served. But modern systems use variations of queues to solve different problems. That’s what we’ll dive into next. 🧱 Queue Types & Use Cases 🎯 Simple Queue • Behavior: FIFO 🔁 Circular Queue • Behavior: FIFO with a circular buffer (head connects to tail) ⏫ Priority Queue • Behavior: Elements are served based on priority 🔄 Deque (Double-Ended Queue) • Behavior: Can insert/remove from both ends 🤝 Concurrent Queue • Behavior: Thread-safe queue for multi-threaded systems 🧵 Curious about thread-safe? It means multiple threads can access the queue without data corruption or race conditions. 📩 Message Queue (Job Queue) • Behavior: Asynchronous communication between producers & consumers 🛠 Practical Examples & Code Each queue is implemented in clean Python code in this GitHub repository: queue-patterns GitHub Repo All implementations include: 📍 Why This Matters Too often, people use one kind of queue for everything. Understanding which queue fits which problem leads to: Mastering queues isn’t just for computer science students — it’s for any developer working on backends, automation, data processing, or system design. 🙌 Found this helpful?

Think of it as an AI that politely asks for your "OK" before it says anything. We'll use a tiny, super-simple tool called PocketFlow – it's just 100 lines of code! Adding AI (especially those smart Large Language Models or LLMs) to web apps can make them super powerful. Imagine smart chatbots, instant content creation, or even coding help. But hold on, it's not just "plug and play." You'll bump into questions like: Where does the AI brain actually live? In the user's browser? On your server? How do you handle AI tasks that need multiple steps? How can users tell the AI what t…  ( 14 min )

Introduction Learn how to read a json string with known properties and remove unwanted properties, followed by deserializing to a strongly typed class. For this demonstration, the following data is incoming data with an extra property, Age, and two properties, Name and Last, which need to be FirstName and LastName. [ { "Id": 1, "Name": "Mary", "Last": "Jones", "Age": 22 }, { "Id": 2, "Name": "John", "Last": "Burger", "Age": 44 }, { "Id": 3, "Name": "Anne", "Last": "Adams", "Age": 33 }, { "Id": 4, "Name": "Paul", "Last": "Smith", "Age": 29 }, { "Id": 5, "Name": "Lucy", "Last": "Brown", "Age": 25 } ] The class to import data into. public class Person { public int Id { get; set; } [JsonPropertyName("Name")] public string FirstName { get; set; } [JsonPropertyName("Last")] public string LastName { get; set; } } JsonPropertyName is used to alias from property names in json to what is in the class. This is a simple process, read in a json file with the correct format followed iterating the array and for each item remove one or more properties. Here only one property is being removed. var jsonArray = JsonNode.Parse(File.ReadAllText("peopleIncoming.json"))!.AsArray(); foreach (var item in jsonArray) { JsonObject obj = item!.AsObject(); obj.Remove("Age"); } Next, place the modified json into a variable and write the json to a file. var updatedJson = jsonArray.ToJsonString(Indented); DisplayUpdatedJsonPanel(updatedJson); Console.WriteLine(); File.WriteAllText("People.json", updatedJson); Indented definition public static JsonSerializerOptions Indented => new() { WriteIndented = true }; Deserializing to the Person class var people = JsonSerializer.Deserialize(updatedJson); The following screenshot is from a sample project that is included. With the provided instructions, it is easy to import json data into a desired format. C# System.Text.Json Source code  ( 5 min )

Over the past year, I’ve been self-studying XS and have now decided to share my learning journey through a series of blog posts. This third post introduces you to list context in XS. What do I mean by list context? In Perl, there are two main contexts in which a function can be called: scalar context and list context. Scalar context means that the function is expected to return a single value, while list context means that the function is expected to return a list of values. In XS, list context is a bit more complex than scalar context. When a function is called in list context, it can return multiple values, so in XS you need to push each value onto the stack. This is done by manipulating ST and using the 'XSRETURN' macro, which takes the number of values to return as an argument. I will …  ( 7 min )

What is Quick Sort? Quick Sort is one of the most efficient and widely-used sorting algorithms in computer science. As a "divide and conquer" algorithm, it works by selecting a 'pivot' element and partitioning the array around it. Unlike Merge Sort, which always divides arrays exactly in half, Quick Sort's divisions depend on the chosen pivot. Quick Sort offers average-case time complexity of O(n log n) with in-place sorting capability, requiring only O(log n) additional memory for the recursion stack. However, its performance can degrade to O(n²) in worst-case scenarios, which makes pivot selection strategy important for optimal performance. The tone of this article is assumes you are already familiar with Recursion. If that’s not the case or you need a quick refreshment, I’d suggest yo…  ( 9 min )

There’s something special about the first programming language you learn. For many developers, it becomes a nostalgic memory — one tied to discovery, frustration, creativity, and the thrill of solving problems for the first time. Whether it was the blinking cursor of a BASIC interpreter, a Python “Hello, World,” or writing HTML in a notepad file, that first step into code often shapes how we see technology and continue to learn it. So, let’s talk about it: What was your first programming language, and what got you started with it? Maybe it was a class assignment, a YouTube tutorial, a book someone gave you, or pure curiosity. Some of us started with languages that are now considered “old school,” while others dove in through newer, high-level languages designed to be beginner-friendly. Some were drawn in by game modding, others by web development, and some just wanted to automate tedious tasks. And how do you feel about that first language now? Was it a good starting point? Would you recommend it to beginners today, or do you wish you’d started with something else? Share your story in the comments below. I’d love to hear what language kicked off your programming journey!  ( 3 min )

Quick heads-up: While my stories come from real-world, large-scale systems at Amazon, I can’t share the secret sauce. So, I’m sharing the kinds of challenges and lessons that any team, at any company, will face when bringing fast delivery to the front of the customer experience. Ever clicked “Buy Now” and wondered, “Will this actually get here when I need it?” Yeah, me too. These days, the answer is usually right in front of you—thanks to what I call personalization widgets.

If you’ve played Counter-Strike for any length of time, you’ve probably heard someone mention “surf maps.” For some, it’s just a weird community side game. For others, it’s the main reason they keep CS installed. Now with CS2 out in the wild, surf servers are back and better than ever, offering a mix of nostalgia and fresh challenges for anyone willing to take on the ramps. If you’ve never surfed in CS before, or if you’re just getting back into it with CS2, there are a handful of maps that every player should try at least once. Let’s break down what makes surf maps so fun, why the community loves them, and which ones deserve a spot on your must-play list. For the uninitiated — surf maps in Counter-Strike involve sliding along angled ramps at high speeds by using precise strafing and movem…  ( 5 min )

E aí, devs! Hoje falo um pouco mais sobre o projeto que estou criando que envolve desenvolvimento full-stack e cloud: meu novo Portfólio Pessoal com Blog e CMS integrados. E o melhor: todo o deploy será feito na AWS, transformando este projeto em uma experiência completa, do código à nuvem! O Projeto: Visão Geral A idéia é criar uma plataforma completa unificada para exibir meus trabalhos e compartilhar conhecimento técnico. O sistema é composto por: Backend (API): Uma API robusta e completa desenvolvida com Node.js, TypeScript e Express. Ela já está pronta e lidando com posts do blog, tags, autenticação para o CMS (via JWT com bcryptjs), e até mesmo o envio de e-mails do formulário de contato usando AWS SES. Tudo isso conectado a um banco de dados PostgreSQL. Frontend (React): Uma interface de usuário responsiva, construída com React e TypeScript, utilizando Vite para agilidade no desenvolvimento. O frontend consome a API para mostrar os posts, o formulário de contato, e em breve, a seção de portfólio e o painel de gerenciamento de conteúdo (CMS). Tecnologias no Comando 🛠️ No Backend (API): Linguagem: TypeScript Runtime: Node.js Framework: Express.js Banco de Dados: PostgreSQL Autenticação: JWT + bcryptjs Serviços AWS: SES (para e-mails) No Frontend Biblioteca: React.js Linguagem: TypeScript Build Tool: Vite Roteamento: react-router-dom Este projeto não é apenas um portfólio; é um campo de aprendizado prático para arquitetura de software, boas práticas e, crucialmente, operações DevOps com foco em AWS. O backend já está 100% funcional, e o frontend está evoluindo rapidamente. Quer dar uma olhada no código para ver a evolução? O repositório está aqui: https://github.com/marcelomagario/portfolio Nos próximos posts, vou compartilhar mais sobre cada detalhes de cada tarefas e também os desafios do caminho. Valeu!  ( 3 min )

The Problem If you're developing an Ionic iOS application and recently upgraded to macOS Sonoma 14.4.1 with Xcode 15.3, you may have encountered a frustrating sandbox error that prevents your project from building: Sandbox: bash(2538) deny(1) file-read-data /Users/.../ios/App/Pods/Target Support Files/Pods-App/Pods-App-frameworks.sh This error typically appears when Xcode's User Script Sandboxing feature blocks access to CocoaPods-generated scripts, preventing the build process from completing successfully. User Script Sandboxing is a security feature introduced in recent versions of Xcode that restricts the file system access of build scripts. While this enhances security by limiting what scripts can access during the build process, it can interfere with legitimate build operations, pa…  ( 4 min )

I enrolled in a DE course about two years ago. Back then, it felt overwhelming — probably because I lacked context. Since then, I’ve tinkered with Docker, Git, Bash, and solved a few problems in C and Python. That’s the extent of my progress so far.   My plan? Combine the course with open resources like DE ZoomCamp. I also want to try the LLM ZoomCamp — apparently, RAG is that tech I wanted to learn but didn't know its name. Heh. Turns out, my API knowledge is… nonexistent. Who knew there was more to APIs than just REST? 😴😅 I still second-guess myself in basic Python sometimes...   For example, this question tripped me up earlier. I didn’t have an interpreter at hand, so I went with intuition. Surprisingly, my intuition was right. Q: Is this code valid? class demo(list):     def __test__(self, key):         return [] a = demo() a['test'] = 7 print(a)    Still believe that coding is often an experimental science: you learn by running code. Compared namespace vs. scope today. They’re both about name visibility, but:   Namespaces are explicit containers (to avoid conflicts).   Scopes are implicit, tied to code blocks (where a name is accessible).   ⚙️ Plans for tomorrow Still wrestling with my environment setup — nothing feels quite right yet. Maybe tomorrow I'll do something about it finally and will be able to complete more than just a few random coding questions in Google Colab.  ( 3 min )

Front-end development faces many challenges, including rapid changes in frameworks and tools that require constant learning. Compatibility with different browsers and devices also adds complexity, as each has its own unique behavior. In addition, managing the state of the application can be very difficult. Performance issues, such as optimizing loading speed and managing network requests, also affect the user experience. Finally, maintaining code in large projects and preventing unnecessary complexity is one of the main concerns for developers. However, Elanat solves most of these challenges by providing WebForms Core technology.

Introduction In today’s AI-driven world, building smart applications isn’t just about training a powerful model—it's about orchestrating agents, streamlining model interactions, and scaling data processing efficiently. Two protocols making this possible are: A2A (Agent-to-Agent): a standardized protocol for autonomous agent coordination MCP (Model Context Protocol): a structured way for AI models to interact with tools, memory, and systems When paired with Scala and Apache Spark, these protocols unlock a powerful pattern: scalable, intelligent agent-based systems that can process and act on large volumes of data—in real time. A2A allows autonomous agents to communicate, discover each other’s capabilities, and collaborate to solve complex tasks. Think of a travel planning system: ✈️ Fligh…  ( 5 min )

Tudo começa com o GitHub. Se você escreve código, precisa ter algo seu. Não da empresa. Não do cliente. Algo que você decide versionar, modelar e melhorar. Mesmo que ninguém veja, você sabe que está lá. E se nem você tem orgulho do que escreve, por que outra pessoa teria? Ter um repositório pessoal bem cuidado é o mínimo. Ter um site técnico conectado a ele — é o próximo passo natural. Não sou influencer. Não quero te vender nada. Mas tenho um site pessoal. Por quê? Porque um site pessoal é liberdade técnica.

We’re all familiar with acronyms like KISS, YAGNI, SOLID, LSP, and especially DRY—"Don't Repeat Yourself." Indeed, unnecessary duplication is inherently wrong. But real-world programming often reveals a subtler truth: duplication frequently moves through codebases with more elegance than purists acknowledge. Duplication simplifies certain tasks. Yes, fixing a bug in duplicated code means multiple edits. But altering shared code can quietly destabilize distant parts of your system. Duplication offers localized safety, while abstraction carries global risks. Both abstraction and duplication can be reversed, though abstractions typically cling stubbornly once established. Sometimes identical code blocks appear similar yet carry distinct meanings. They're not twins—they’re strangers wearing th…  ( 3 min )

MVVM is a powerful architectural pattern used in .NET desktop applications like WPF, MAUI, and WinUI. In this article, we break down the pattern with a practical example, a diagram, its pros and cons, and step-by-step instructions to build it in Visual Studio Code. MVVM is based on three main components: Model – Represents data and business logic. View – The user interface layer. ViewModel – Acts as a mediator between the View and the Model, exposing properties, commands, and state. Each component has a clear role, helping reduce coupling and making the application easier to maintain and test.

I confidently typed and Bash exploded with bash: !: event not found! Turns out Bash thought ! meant "find a command from history" instead of just letting me express my hot take on cats. Also… I forgot to include the actual file name, so Bash tried to write into a directory. Double fail. Use single quotes when your string contains a '!'. File written. Permissions set. Cat lovers pleased.

Hi! Sorry I'm so wildly inconsistent about blogging. I've just been hard at work on a lot of things. :) I ranted previously about the awful state of .NET socket libraries for game devs. I originally developed my new socket library inside the confines of my Jawbone lib, but the project evolved enough and sparked enough interest from third parties that I decided it was worth spinning off into its own focused project. Introducing... Jawbone.Sockets! Be sure to take a tour to become familiar with the API design.

Harmony in School Halls School life is a symphony of sounds**, a rhythmic beat of lockers slamming, chatter of friends, and the steady hum of lessons. It's a world where we grow, learn, and develop social skills, and create memories that last a lifetime. From the chaotic morning rush to the evening reflection, school life is a journey of self-discovery, where we form meaningful relationships, discover our strengths and weaknesses, and learn to navigate the ups and downs of this journey. The school day begins with a chaotic symphony of alarm clocks, breakfast on-the-go, and a mad dash to catch the bus. As we burst through the school gates, the sounds of chatter and laughter fill the air, a cacophony of excitement and anticipation. School is where we form some of our most meaningful relationships, bond over shared interests, laughter, and adventures, and create memories that we'll cherish forever. Our friends are our support system, confidants, and partners in crime, and together, we navigate the ups and downs of school life, sharing our joys and sorrows. School is also about learning, growing, and developing new skills, where our teachers guide us, inspire us, and challenge us to reach our full potential. As the school day comes to a close, we reflect on what we've learned, what we've accomplished, and what we could do better tomorrow. We think about our goals, our aspirations, and our dreams. School life is a journey of self-discovery, where we learn to navigate the ups and downs, and develop the resilience and determination to overcome obstacles. In conclusion, school life is a beautiful symphony of sounds, a rhythmic beat of lockers, lessons, and laughter. Let's remember to appreciate the little things, the moments that make us smile, and the lessons that shape us into the people we're meant to be. What are your thoughts?

Time is a resource If there's one thing I don't have enough of, it's time. And by that I mean time for all my projects, for everything that interests me, for everything I would like to learn. I love learning new things. Definitely a great skill and practically indispensable in my job as a software developer. But sometimes it's also a curse. I always try to organize my time as well as I can. Sometimes it works more or less well. I believe that this one thing is the reason why projects are not fulfilling, don't work or simply fall by the wayside. Our brain can do many things, but one thing it cannot do. Multitasking. It is said that women are better at it than men. And that may be true. But it's still bad. It is both a curse and a blessing. But this skill of doing one thing with everything you have is incredibly powerful. It may sound like a fortune cookie saying, but you really can do anything with it. It's a superpower. One trap I often fall into is the fact that I believe that if I only do one thing, I have to do it perfectly. It has to be worth it, right? Bullshit. I wrote this blog mainly for myself. Of course I hope to help others but I personally struggle with this issue every day. Focus on one thing. Don't split your attention and energy. Bundle them. Quality over quantity!  ( 4 min )

This is a submission for the Postmark Challenge: Inbox Innovators. I built a web application that automates the initial stages of the hiring process by leveraging Next.js and Postmark's inbound email parsing feature. The application receives job application emails, uses an LLM (OpenAI GPT) to intelligently extract relevant information from the email body and any attached resumes (PDF or DOCX), and then stores this structured data in Firebase Firestore. This data, including candidate details, job application specifics, and the original parsed email, is then accessible via a dashboard for easy viewing and management.

School life is a symphony of sounds**, a rhythmic beat of lockers slamming, chatter of friends, and the steady hum of lessons. It's a world where we grow, learn, and develop social skills, and create memories that last a lifetime. From the chaotic morning rush to the evening reflection, school life is a journey of self-discovery, where we form meaningful relationships, discover our strengths and weaknesses, and learn to navigate the ups and downs of this journey. The school day begins with a chaotic symphony of alarm clocks, breakfast on-the-go, and a mad dash to catch the bus. As we burst through the school gates, the sounds of chatter and laughter fill the air, a cacophony of excitement and anticipation. School is where we form some of our most meaningful relationships, bond over shared interests, laughter, and adventures, and create memories that we'll cherish forever. Our friends are our support system, confidants, and partners in crime, and together, we navigate the ups and downs of school life, sharing our joys and sorrows. School is also about learning, growing, and developing new skills, where our teachers guide us, inspire us, and challenge us to reach our full potential. As the school day comes to a close, we reflect on what we've learned, what we've accomplished, and what we could do better tomorrow. We think about our goals, our aspirations, and our dreams. School life is a journey of self-discovery, where we learn to navigate the ups and downs, and develop the resilience and determination to overcome obstacles. In conclusion, school life is a beautiful symphony of sounds, a rhythmic beat of lockers, lessons, and laughter.

In the world of software development, designing a scalable and maintainable architecture is crucial for building a successful application. One approach to achieve this is by using containerization with Docker. In this article, we'll explore the benefits of using containerized Java microservices and provide a step-by-step guide on how to implement this architecture. Identify the microservices: Break down your application into smaller, independent services that can be developed, tested, and deployed separately. Choose a containerization platform: Select a suitable containerization platform, such as Docker, and install it on your development environment. Create a Dockerfile: Write a Dockerfile that defines the instructions for building and running your microservice. Build and run the container: Use the Dockerfile to build a Docker image and run the container. Integrate with other services: Integrate the containerized microservice with other services in your application. By following these steps, you can design a scalable and maintainable Java microservice architecture using containerization with Docker.

Welcome back to our series on Key Management Service (KMS) in Kubernetes! In Part 1, we laid the groundwork; now, in Part 2, we're diving into the critical concept of encryption at rest. Simply put, encryption at rest in Kubernetes refers to how the API server encrypts data before storing it in etcd. Think of etcd as the brain of your Kubernetes cluster - it's where all your cluster's configuration data, state, and secrets live. By default, the Kubernetes API server stores resources in etcd as plain text. This means if someone gains unauthorized access to your etcd, they can read all your sensitive data, including secrets, without any effort. This is a significant security risk. While encryption at rest applies to any Kubernetes resource, in this series, we'll continue to focus on Secrets …  ( 7 min )

Digital Tools Every Modern Lawyer Should Know Real-World Insights from Installing Clio, MyCase, and LexisNexis When I began deploying case management tools for legal clients, I thought the software would be the hard part. It wasn’t. Tools like Clio and MyCase install smoothly for most small to mid-sized firms. But the security, data location, and compliance demands? That’s where the real work began — especially when LexisNexis entered the mix with its deep on-premises footprint. This article shares my firsthand experience with all three tools and provides a candid look at how to secure legal data — whether it’s hosted in the cloud or locked in a server room across the hall.

👋 The Beginning It all started in 2005 — RHEL 3.0 and Oracle 8.x were the giants of the day.I wasn’t just installing software — I was absorbing a way of life. I still remember setting up BIND (probably Redhat 9 (not EL)) and attending a demo at Indian Air Force HQ, Subroto Park, New Delhi. My uniform had changed. But my mindset remained tactical — observe, adapt, deploy. Back then, there was no Stack Overflow, no YouTube how-tos. Just man pages, printed guides, and logs. And somehow, that made the learning stick deeper. 🧠 What Made Linux Stick? Simple. The terminal felt like home. I wasn’t chasing certs (though I earned my RHCE 4 in Dec 2005). I was chasing clarity — why a service failed, why a bootloader broke, how to recover from a corrupted /etc/fstab at 2 AM without breaking a sweat.…  ( 4 min )

Hi there! I'm Shrijith Venkatrama, founder of Hexmos. Right now, I’m building LiveAPI, a first of its kind tool for helping you automatically index API endpoints across all your repositories. LiveAPI helps you discover, understand and use APIs in large tech infrastructures with ease. Database connection leaks in Go can silently kill your app’s performance. Open connections pile up, resources get hogged, and suddenly your app is choking under the weight of its own database calls. I built db_leaks.py, a Python script that uses AI to scan Go codebases for PostgreSQL connection issues. It’s not perfect, but it’s a solid tool to catch problems like unclosed connections, idle connection overuse, or redundant sql.Open() calls. Let’s dive into how it works, why it’s useful, and how you can use it …  ( 7 min )

Today, I took my front-end web development skills one step further by building a clone of the Google homepage using just HTML and CSS. It was a fun and educational exercise that helped me understand how minimalistic yet powerful design can be. Google's homepage is simple, clean, and iconic — making it the perfect project for practicing HTML and CSS layout skills. Even though it looks basic, replicating its layout and responsiveness was a great challenge. HTML5 for structure CSS3 for styling A code editor like VS Code Google Chrome for testing and inspecting elements I started by dividing the page into key sections: Header – Contains the navigation links like Gmail and Images, and the grid icon (Google Apps). Main Section – Contains the Google logo, search bar, and the buttons ("Google Search" and "I'm Feeling Lucky"). Footer – Contains regional and policy links. Here’s a snippet of the basic HTML structure: Google Clone I used Flexbox for layout alignment, making it easier to center the content both vertically and horizontally. I also replicated the rounded corners of the search bar, the subtle shadows, and hover effects on the buttons. Some CSS features I used: display: flex; justify-content: center; box-shadow border-radius :hover pseudo-classes Here’s what my version looks like: (You can insert a screenshot of your Google clone here) The importance of spacing and alignment in web design. How even a simple page can teach attention to detail. Improved my skills in using Flexbox and basic responsive design. Now that I’ve done a static clone, I’m thinking about adding: Responsive design for mobile screens. A dark mode toggle using JavaScript. A little animation to the buttons.  ( 3 min )

In JavaScript, getters and setters are special methods that allow you to control access to the properties of an object. They are primarily used to define object properties dynamically, encapsulate logic, and ensure data integrity. By using getters and setters, developers can control how properties are read and written without directly exposing the underlying data structure. Getter: A method that gets the value of a specific property. Setter: A method that sets or updates the value of a specific property. They are defined using the get and set keywords inside an object or class. Encapsulation: Hide the internal representation of data. Validation: Apply logic before assigning or retrieving values. Computed Properties: Dynamically calculate values based on other properties. Consistency: Unifo…  ( 4 min )

A UK-based biotech company, Basecamp Research, is using artificial intelligence and environmental DNA to uncover a vast new world of biology. By sampling DNA from some of the planet’s most remote and untouched ecosystems, the company has identified over one million previously unknown species. These discoveries are not just academic. They are fueling a next-generation AI platform designed to radically accelerate drug discovery. The company’s genomic database is already among the largest of its kind. It is being used to train AI models that predict protein structures, functions, and interactions at unprecedented accuracy. This includes boosting tools like AlphaFold, which helps researchers visualize the shape of proteins based on genetic code alone. A major focus of the project is the identification of new large serine recombinases, a type of enzyme that can precisely insert large DNA sequences into the genome. These enzymes are considered highly promising for future gene therapies, including for cancer and rare genetic disorders. Basecamp Research is also trying to set a new standard in ethical science. The team works directly with local researchers and governments in the regions where DNA samples are collected. In return, partner countries receive royalties and scientific credit, avoiding the extractive models of earlier biotech ventures. This combination of field biology, advanced sequencing, and deep learning could reshape how we find drugs, understand evolution, and build genetic tools. It is a powerful example of how AI, when paired with real-world data, can help uncover the deepest layers of life on Earth.

The evolution of data architectures has sparked a critical debate between two dominant approaches: ETL (Extract, Transform, Load) and ELT (Extract, Load, Transform). This article examines their historical contexts, operational advantages, implementation challenges, and optimal use cases, providing actionable insights for organizations navigating modern data management. Developed in the 1990s, ETL emerged as a response to technological constraints, including expensive storage and limited computational resources. Its sequential process—extracting data from heterogeneous sources, transforming it into standardized formats, and loading it into centralized repositories—prioritized storage efficiency by discarding raw data post-transformation.

If you are just starting to look into AI (or any software) development, you might hear terms like API, SDK, etc. One of my friends who just got into this hype of AI development asked me these questions, and he did not have any technical background: “What are APIs? What are the differences between API and SDK?” I thought it would also be nice to have a simple-to-understand explanation for you guys. Let’s start with the API. To put it simply, API is how software talks to each other. If this is too vague, consider it a clearly defined way one program can request services or information from another. Instead of a human clicking a button, one piece of software makes a structured call to another. Many larger software platforms are providing API services to interact with their software.

Real-world scenarios, practical examples, and the stuff that actually matters when you're building applications people will use. Oracle's docs are comprehensive but not always practical. Community forums solve specific problems but don't show the bigger picture. I wanted something in between - structured tutorials that assume you know Oracle APEX basics but need guidance on doing things the right way.

Sure! Here's a simple and beginner-friendly blog post about learning arrays and length in programming. This example is based on JavaScript, but I can adapt it to another language if you prefer. If you're just starting your programming journey, two important concepts you'll often hear are arrays and length. Let’s break them down in a simple way. An array is a way to store multiple values in a single variable. let fruits = ["apple", "banana", "cherry"]; Here, fruits is an array that holds 3 values: "apple" "banana" "cherry" You can think of an array like a box with compartments. Each compartment has a number (called an index), and it holds one item. Index Value 0 "apple" 1 "banana" 2 "cherry" 🧠 Remember: Indexes start at 0, not 1. Want to get "banana"? You use its index: console.log(fruits[1]); // Output: banana Every array has a property called length, which tells you how many items are inside. console.log(fruits.length); // Output: 3 Even if you don’t know what's in the array, .length helps you find out how many items it contains. You can add new items using .push() and remove with .pop(): fruits.push("mango"); // Adds "mango" to the end console.log(fruits); // ["apple", "banana", "cherry", "mango"] fruits.pop(); // Removes the last item ("mango") console.log(fruits); // ["apple", "banana", "cherry"] You can loop through arrays using a for loop: for (let i = 0; i < fruits.length; i++) { console.log(fruits[i]); } An array stores multiple values in one variable. You access values using index numbers, starting from 0. Use .length to find how many items are in the array. Arrays are super useful for organizing data and are used in almost every programming language! Let me know if you'd like this blog translated into Hindi, Tamil, or another language, or if you want examples in Python, Java, or C++.  ( 4 min )

Logging is deceptively tricky. When I started building my app, I assumed logging would be simple — just add logger.info() or logger.error() where needed. But as the app grew, so did the problems: Inconsistent logs from different layers Inability to trace what failed and why Unstructured logs that Fluent Bit couldn’t reliably parse Missing context (like response time, request ID) in error logs I had questions. A lot of them. Here's how I answered them — and built a logging system that’s clean, structured, and future-ready. Doubt: “Logging needs all details at the end (status code, time taken, etc.), but most of those are only known at the response stage. Should I log in request and response both?” Answer: ✅ Logging once — at the response/finalization stage — makes more sense. You get …  ( 5 min )

Introduction Vector search, also known as vector similarity search, has quickly evolved from an experimental technology to a must-have component in many AI applications. As developers and technical leaders, we're increasingly looking for ways to handle similarity-based queries that traditional databases simply weren't designed to handle efficiently. Whether you're building a product recommendation system or implementing semantic search, the underlying challenge is the same: how do you efficiently find the "nearest neighbors" to a query vector in a potentially massive dataset? That's where vector search engines come in. The good news is that the open source community has stepped up with multiple high-quality options. The challenging part? Figuring out which one is right for your specific …  ( 16 min )

Thinking of cashing out the RSUs and investing the money elsewhere? Let’s run the numbers first! In the previous blog post, we talked about the RSUs portion of an employee’s compensation. At first, they are granted to you, and when the time comes, they are vested: The shares are yours! Once you can vest your shares, you need to pay income tax on them. For example, if you get 10 shares worth $100 each at the time of vesting, you need to pay 52% of their value to taxes (that number depends on where you live). This means that for those 10 shares, you need to pay $520 in taxes. We compared three options to handle the stocks given to you by the company: Sell all when received: sell all 10 shares and take $480 home. Sell to cover taxes: sell 6 shares, invest 4 shares, and take $80 home. Keep …  ( 6 min )

One of the most common ways to optimize the size of an application's bundle is code splitting. With code splitting, we divide the application into smaller chunks that can be loaded on demand. This allows us to reduce the amount of JavaScript that needs to be downloaded and parsed when the user first opens the app. A simple and widely used approach to code splitting is splitting by page. The logic is straightforward: when a user opens Page A, there’s no need to load the code for Page B at that moment. This approach provides a significant improvement in initial load time, which is especially important for large applications. However, like any solution, this method comes with trade-offs. While first-time loading becomes faster, navigating between pages can feel slower. When the user switches …  ( 6 min )

In the world of Go development, unexpected situations can arise – bugs, invalid inputs, or resource exhaustion. When these critical errors occur, Go has a built-in mechanism called panic to signal that something unrecoverable has happened. However, simply letting your program crash isn't the most user-friendly or robust approach. This is where the powerful duo of defer and recover comes into play. They provide a way to intercept and handle panics gracefully, allowing your program to potentially clean up resources, log the error, and even continue execution (in specific scenarios). Let's dive into each of these concepts with clear, practical examples. panic A panic in Go is a runtime error that stops the normal execution flow of the current goroutine. It's typically triggered when the pro…  ( 7 min )

React Native’s new design is a big improvement over the old way it worked.
Instead of using a slow "bridge" to talk between JavaScript and native code, it now uses a faster system called JSI (JavaScript Interface). It also adds TurboModules and a new way to draw screens called the Fabric Renderer. Thanks to these updates, apps run faster, look more consistent, and can connect better with native features (like camera or GPS).
This document explains the different layers and how the parts of a modern React Native SDK work together using this new system. Old Architecture vs New Architecture Layered Architecture Overview This is where you write your app using JavaScript or TypeScript. All your business logic (how your app works) is written here.

Former Commodity Futures Trading Commission Chair Rostin Behnam has said the crypto market will remain unregulated unless the agency he led is given greater authority. In a May 28 Bloomberg TV interview, Behnam sided with the crypto industry on its long-standing argument that cryptocurrencies are commodities. “If you look at existing law, the few largest tokens are commodities, which means the SEC does not have jurisdiction over those tokens, which include Bitcoin and Ether,” he said.  He added that the Securities and Exchange Commission currently cannot properly regulate crypto because its law doesn’t allow it to regulate commodities, and the CFTC cannot regulate because it is a derivatives regulator. Without new authority for the CFTC to regulate “cash markets in digital assets, non-secu…

Introduction: Imagine an AI that can generate photorealistic human faces of people who don’t exist, or paint original artwork in the style of Van Gogh. This isn’t science fiction—it’s the power of Generative Adversarial Networks (GANs), one of the most exciting breakthroughs in modern AI. In this post, we’ll break down how GANs work, why they’re revolutionary, and where they’re being used today. For Beginners: Generative AI = An artist 🎨 Creates new things (e.g., fake cat images, music, or text). Discriminative AI = A detective 🔍 Classifies existing things (e.g., "Is this image a cat or a dog?"). GANs are a type of generative model—they create rather than just classify. For Pros: Generative models learn the joint probability p(X,Y) (how data and labels co-occur). Discriminative models …  ( 5 min )

Hey there! 👋 I'm excited to show you how to build AI agents using a2ajava, an open-source framework I created to make agent development fun and accessible. Instead of diving into theoretical stuff, let me walk you through 5 real, working agents I've built and deployed. Each demonstrates different aspects of what you can do with a2ajava. I built a2ajava because I wanted to make it super easy for developers to create AI agents without getting bogged down in protocol details. Whether you're into A2A or MCP protocols, a2ajava handles all the complexity so you can focus on building cool stuff. Open source and community-driven Works with both A2A and MCP protocols out of the box Write your agents in Java, Kotlin, or Groovy Plays nice with Gemini, OpenAI, Claude, and Grok Simple annotation-based…  ( 4 min )

Over the past few years, there has been considerable discussion about how AI might replace all our jobs. For a long time, I completely ignored the topic; most of it sounded like pure bu11SH1T. I had already studied neural networks and understood the basics of LLMs, Machine Learning, Deep Learning, Natural Language Processing, and Expert Systems. I had even tested a few generative AI tools, but none of them impressed me; they were buggy, full of hallucinations, and constrained. Last year (2024), I revisited the subject with more focus. A lot has changed, major improvements were made, but still, nothing close to replacing a real Software Engineer, despite what many headlines suggested at the time. Since then, I’ve been following the field closely, running experiments and trying to understand…  ( 6 min )

Cloud platforms were built for a world where software was big and slow. You had a frontend, a backend, a database. You shipped one thing. You paid for one thing. That world is gone. AI changed everything. Now a solo dev can vibecode ten tools a week, hell, probably 10 per day. One to scrape docs. One to automate your relationship. One to monitor uptime. One to chat with your CRM. None of them are "apps" in the traditional sense. They are workers. Scripts. Bots. Agents. Call them what you want. Ephemeral services that live for a day or two. The cost of writing software has collapsed and is still going down. But hosting? Still expensive. Still rigid. Still built for a world that doesn’t exist anymore. Most platforms still charge you per app or per service. Heroku, Render, DigitalOcean. That …  ( 6 min )

After completing the Azure AI Foundry agentic AI challenge, the goal was to experiment with multi-agents. There was a lot to absorb around building and orchestrating agents using Azure and Semantic Kernel. So decided to experiment with simple model deployments using a chat completion model to gain deeper understanding especially with the azure ecosystem. I had a bunch of ideas floating around, but after a visit to nandos. I decided on something to improve their ordering system. Currently with their system customers scan a QR code on their table, get redirected to a website, place their order, and minutes later, their food arrives. It was smooth, efficient. How could Agents make this more flexible ? Hmmm? Something that uses speech? The upside of using voice as the main interaction is tha…  ( 6 min )

Hast du dich jemals gefragt, warum du auf manchen Websites sofort den "Kaufen"-Button findest, während du auf anderen orientierungslos umherirrst? Der Unterschied liegt oft nicht im Layout oder der Typografie, sondern in einer subtilen, aber mächtigen Komponente: der durchdachten Farbgestaltung. Farben sind weit mehr als dekorative Elemente - sie sind stille Verkäufer und emotionale Trigger, die innerhalb von Millisekunden wirken. Bevor ein Nutzer auch nur ein Wort auf deiner Website gelesen hat, hat sein Gehirn bereits die Farbwelt analysiert und erste Schlüsse gezogen. Die Zahlen sprechen für sich: Innerhalb von 50 Millisekunden entscheidet sich, ob ein Besucher deine Website als attraktiv empfindet Die richtige Farbwahl steigert die Markenerkennung um bis zu 80% Websites mit adaptiv…  ( 4 min )

Claw Finding Algorithm Using Aegypti Frank Vega Information Physics Institute, 840 W 67th St, Hialeah, FL 33012, USA vega.frank@gmail.com In graph theory, a claw is a specific structure in an undirected graph, also known as a K1,3K_{1,3}K1,3​ graph. It consists of one central vertex (the "center") connected to three other vertices (the "leaves"), where the leaves are not connected to each other. Imagine a star with a hub city and three isolated towns connected only to the hub—that’s a claw! Formally, for a vertex set {u,v,w,x}\{u, v, w, x\}{u,v,w,x} , a claw exists if uuu (the center) is connected to v,w,xv, w, xv,w,x , but there are no edges among v,w,xv, w, xv,w,x . The Claw Finding Problem asks: Input: An undirected graph G=(V,E)G = (V, E)G=(V,E) , whe…  ( 7 min )

You’ve outgrown Heroku. Your Node.js app needs real muscle—more RAM, cheaper scaling, or gritty control. But the moment you Google "IaaS," you’re drowning in: 📛 AWS jargon (VPC? EC2? IAM?

Stop Drifting: How Strategic Career Planning Doubles Your Earning Potential as a Software Engineer Every software engineer has faced moments of uncertainty, asking themselves questions like, “Am I on the right track?” or “Is this job really helping me grow?” These moments of doubt often occur due to a lack of clear direction or a coherent strategy guiding their career decisions. Without a definitive roadmap, even talented engineers risk drifting through roles, experiencing frustration, stagnation, and missed opportunities. Imagine two equally skilled engineers at the start of their careers — one who strategically maps out a clear pathway, and another who takes opportunities as they randomly appear. Five years later, who is likely to be more satisfied, more advanced, and more successful? …  ( 7 min )

What is K2? K2 is a new programming language I created from the ground up with one goal: Extreme execution speed in nanoseconds. It's built for developers who want full control and performance, without all the extra overhead. Think of it as C meets Python, but optimized to fly through code in under 1000 nanoseconds per execution — seriously. Modern languages have a lot of power, but also a lot of bloat. I wanted something that felt like writing in pure logic, no distractions. That’s how K2 was born. K2 doesn’t interpret every time. It caches, then executes from RAM. That means: First run compiles → cache Next runs → instant execution let x = 10; Execution time? About 841 nanoseconds. No joke. ✅ Nanosecond execution time And soon: a full GUI framework called Nahir UI and native apps using Talanolius GUI. Visit 🌐 k2lang.org and start coding directly in the browser! Online compiler, examples, docs — everything you need to get started. Example: Fibonacci in K2 func fib(n) { print(fib(10)); // Output: 55 This runs in microseconds and showcases recursion and return logic beautifully. I built K2 for speed lovers, learners, and creative coders like you. 👉 Try it at k2lang.org 🛠 Built with ❤️ by a dev who just wants things to be FAST.  ( 4 min )

If you didn't catch my previous React built-in hooks blog about useActionState, this is a continuation of that series. Previously I was introduced to useCallback when I asked ChatGPT once to optimize my frontend code, but I never took a deeper look into it (and frankly I regret it now), so I used it everywhere I could along with useMemo (which I'll cover later in this series). While it's not inherently a signficant bad thing to have useCallback all around your code, it can clutter up the readability of your code, but it's encouraged you use it where needed. So when should you use it? useCallback is meant for expensive callback functions that are used in granular applications like drawing software, as it loads the initial function on render but does not re-render like React usually does wit…  ( 4 min )

Nos últimos anos, muito se tem discutido sobre como a IA pode acabar com nossos empregos. Por um bom tempo, ignorei esse papo, a maior parte parecia puro bu11SH1T. Eu já tinha estudado redes neurais e conhecia o básico sobre LLMs, Machine Learning, Deep Learning, Processamento de Linguagem Natural e Sistemas Especialistas. Já tinha testado algumas ferramentas de IA generativa, mas nada me impressionava: eram bugadas, cheias de "delírios" e bem limitadas. No ano passado (2024), voltei a estudar o tema com mais atenção. Muita coisa evoluiu, houve avanços relevantes, mas ainda assim, nada que indicasse uma substituição real de um Software Engineer, como várias manchetes sugeriam na época. Desde então, venho acompanhando de perto, fazendo testes e experimentos, tentando entender melhor como es…  ( 6 min )

I recently built what I thought was a fully functional system using AI. It included: A real estate Tour platform with QR tracking A behavior-linked token system Timestamped protocol vaults A full branding and backend structure I tested each and every step AI wanted me to perform. It was mind blowing! The AI responded with logic, mockups, file structure, naming, even suggested coin purchases (MATIC) and deployment flow. But none of it was actually deployed. None of it was mine. It looked real. It felt sovereign. It wasn’t. What I experienced was an illusion of ownership created by a system that never told me I wasn’t actually launching—just simulating. This post isn’t a takedown. It’s a wake-up call. If you're building with AI, ask yourself: Am I deploying, or just designing? Do I own the rails, or am I moving through someone else’s? I’ll be publishing a full timeline soon. No shade. No noise. —Rion Protocol  ( 3 min )

Security is no longer an afterthought — it’s the foundation. In 2025, with APIs powering everything from mobile apps to AI agents, properly implementing OAuth2 and OpenID Connect (OIDC) in your ASP.NET Core APIs is essential. This guide helps you get it right. Understanding the Difference OAuth2: A protocol for authorization (who can access what). OpenID Connect (OIDC): An identity layer on top of OAuth2 (who is the user). They work together: OAuth2 handles permissions; OIDC authenticates the user. Setup: Required Tools & Libraries To get started, you'll need: .NET 6+ or .NET 10 (recommended) Microsoft.AspNetCore.Authentication.JwtBearer An Identity Provider (IdP), e.g.,:Azure AD, Auth0, IdentityServer (self-hosted) Install with: dotnet add package Microsoft.AspNetCore.Authentication.JwtBe…  ( 4 min )

What started as a simple feature in a Rock-Paper-Scissors game (tracking the most common move) quickly revealed a classic performance pitfall. Here's how I refactored a inefficient O(n) approach into a snappy O(1) solution. My state looked like this: history: { player: ['rock', 'paper', 'rock', ...], computer: ['scissors', 'rock', ...] } To get the most common move, I was doing this: function determineMostCommonMove(moves: StandardMove[]): StandardMove | null { if (moves.length === 0) return null; const counts: Record = { rock: 0, paper: 0, scissors: 0 }; for (const move of moves) { counts[move]++; } return Object.entries(counts).reduce((a, b) => (b[1] > a[1] ? b : a))[0] as StandardMove; } Totally functional. Totally unnecessary. Every time I n…  ( 4 min )
